Mythbusting Global Warming

There are numerous debates not only in our government but also in our communities that GLOBAL WARMING is just a myth. Let us explore the sides of the changes that are happening in our planet and find out who’s causing it.

The US is home to 5.7% of the world entire population. Can you imagine how much carbon dioxide emissions the country alone produces?

environmental pollution

About 25% of the CO2 emissions on earth is contributed in the US alone. With other countries both developing and developed add to these emission the earth’s atmospheric layer is broken down bit by bit. Hot air is trapped within the earth that may cause extreme heat or cold in numerous places all over the globe.

Prices of commodities did not increase alone, factors such as number of population, increase of demand and supply of both raw and recycled material has significantly hit the roof. Unstable markets pose as a threat to both small and large business wherein trade is vital. Along these changes come global warming wherein our oceanic waters have warmed to a full degree Fahrenheit since the 70’s.

If the artic ice could only yell help I melting!!! It will. With its rapid disappearance, the region might experience summer by 2040 or earlier. Species who live in this type of habitat would surely be affected by the the loss of sea-ice. Creatures and plant below our seas are also affected by climate change. Coral reed which are know to house indeginous cultures and marine species are highly sensitive to the changes in water temperature. In response to the stress brought forth by these phenomenon, coral reefs die and so is the biodiversity that comes with it.

If global warming continious, we would feel the direct heat of the sun in 400 years. You might re-think and say who cares I am gone by then but hey don’t you want the future generation to see what the real beauty our planet beholds? All human beings are the current contributors of planetary warming, no matter how big or small the contributions towards hazardous emission that depletes the environment is, it is still a major factor.

The propose change our counter for climate change is to begin with one self. We must reduce our emission and save the environment resources. There are numerous proposed alternatives that would aid as viable solution to the growing effects of global warming today.

Turning Trash Into Treasure

From landfills to agricultural waste, people all over the world are turning trash into treasure using Biomass Gasifiers. An ingenious process that can produce 3 valuable resources, electricity, drinking water and fertilizer. Companies can also earn profits on waste removal fees, making this one of the best ways to turn one man’s trash into another man’s treasure. From humble inventions that can be used in villages to large gasification plants that can provide green energy to tens of thousands, we are going to show you some examples of how biomass gasification is changing the planet and then we are going to show you just exactly how the technology works.

The story starts in Rajasthan. India; Population 68 million (2011 census). Here you can find a biomass gasifier in every village that can run a 30hp generator for 1 hour on 20 kilograms of waste. Designed by Rai Singh Dahiya, a local peasant with no formal training, this device has already won him many awards. His gasification device is small, portable, affordable and the best part is that it is fueled by something that Rajasthan has plenty of, agricultural waste.

Industrial Trash Saves Company Millions

Japan Waste Gasification PlantKani, Japan is home to the Daio gasification plant, that turns left over waste from their paper plant into Syngas. The plant reduces energy cost and emissions while solving their abundant waste problem. The savings result in millions of dollars per year in electricity, waste removal and emission tariffs.

Landfill Waste Converted into Green Energy

Pampanga, Philippines located just two hours outside of Manila has just over 5 hectares of rotting landfill waste that is killing the local environment and putting millions of tons of methane gases into the atmosphere each year. This is also home to another company that is making strong profits turning trash into treasure. In the picture above members of the local government and green energy investors break ground. This Biomass gasification plant , when completed is expected to produce enough clean energy to power 60,000 homes, clean up overfilled landfills and reduce Philippines’ carbon footprint at the same time.

How Gasification Turns Trash Into treasure

Now we’ve seen some examples, lets look at how the process works. Not all gasifiers are created equal as the technology can be used in so many different ways.  Gasification can clean the environment from waste while producing byproducts such as electricity, fertilizer and even clean drinking water. Bio Gasification is the process of heating materials in a controlled environment without igniting combustion. The result is a gas that can be used as fuel as well as heat that can clean water and/or power a steam turbine. Currently no other form of green energy has so many collateral positive effects on nature.

Invest in Gasification Plants

We are going to take a look at why gasification plants are the hottest and most promising green energy investments for 2012. Just check out the headlines for Invest in Gasification plants and you will see just how popular it is. Large companies and even governments all over the world are getting in on the action and now InvestinGreenEnergy.com aims to bring this information to potential investors.

POSCO, a South Koren steel company, announced earlier this month that they are investing in a new gasification plant to be built in 2012 in Mongolia. This is a joint venture with a Mongolian green energy firm. A company spokesperson announced the signing of the Memorandum of Understanding (MOU) to Dow Jones Newswires however, no further details have been disclosed.
Gazprom is the largest company in Russia and also the largest extractor of natural gas in the entire world. Earlier this month they announced their plans to invest 500 million rubles for the construction of new gasification facilities in Russia. This is in addition to spending 1.5 billion rubles between 2007 and 2010. A clear indication of their bullish perception on gasification plants as a source or green energy.

Newest Gasification Plants

Yet another promising gasification investment is in the Philippines. TGEG is leading the pack with the construction of a Biomass Gasification plant that uses landfill waste and converts it into green energy and fertilizer. They have been granted over 5 hectares of land by local governments and with the Philippines’ out of control waste problems, they have plenty of landfill waste to fuel their plants for generations to come. Their income will come from waste removal services, clean drinking water produced as a byproduct, fertilizers also produced as a byproduct and of course the feeding of electricity back into the national grid. Their facility is already inder construction however, they are expected to continue raising money for private placement clean into 2012.

Biomass Gasification: Organically Derived Combustibles at Work

The use of biomass-gasification to produce energy is by no means a modern invention. In fact combustible gasses produced from feed fuels powered blast furnaces almost 200 years ago. It was not long before the true versatility of the process began to be exploited and used to generate heat and power. Europe was the first to introduce gas systems, which relied on  peat and charcoal as feed material.

…availability of oil reduces interest in biomass gasification

Towards the beginning of the 1900s oil was becoming the dominant fuel of choice and was replacing older systems at a rapid rate. However, there was a shortage in petroleum supplies during the World Wars which led directly to re-introduction of biomass gasificationsystems. By 1945 the gas generated from biomass gasification was being used to power everything from trucks and buses to agricultural and industrial machinery. Research suggests that there are close to 1 million vehicles currently running on the producer gas generated from the biomass gasification process.

…Sweden continues research on biomass gasification to this day

The end of World War II greatly increased the availability of fossil fuels like oil, coal, and gasoline leading directly to an overall decline in the biomass gasification industry. Interestingly, the Swedes continued to work diligently on producer biomass gasification technology.  Efforts to reduce reliance on oil was drastically increased as a response to the 1956  Suez Canal crisis. As a result a decision was made to permanently include gasifiers in Swedish strategic energy plans. The National Swedish Institute for Agricultural Machinery Testing promptly began research and development related to the production of wood gasifiers in Sweden which continues to this day.

The oil crisis of the early 1970s gave way for the next boom in interest in small scale biomass gasification systems.  However, once oil prices returned to normal interest in research and development quickly dissipated.  Today there are close to 70 manufacturers around the world and around 30 in the United States. Currently, Gasifier and Equipment Manufacturing Corporation in Philippines is the world’s largest gasification manufacturing facility. GEMCOR produces over 3000 units per year ranging in size from 10-250 kW. While the company’s efforts have primarily been aimed at irrigation pumps and power generating sets, GEMCOR’s engineers have even designed gasifiers for direct heat applications.

Solar Heating Systems

The sun’s power can be used in many different ways and one of them is through solar heating systems. This systems goes through the processes that converts solar energy to heat. Heat can be produced through the use of solar thermal collectors which have three types. These are low, medium and high-temperature collectors.

The low-temperature collector, are flat plates that are used in heating swimming pools and even for heating and ventilation. The medium-temperature collector are also made of flat plates that are used for the purpose of heating air or water for homes and business establishments. The third-type which is the high-temperature collector do not use flat plates, instead, it uses mirrors and lenses that concentrates the solar power harnessing. The high-temperature collector is used to generate electricity. It is important to note that thermal collectors are different from photovoltaics.
solar thermal system
The use of solar thermal systems are now widely used, mainly for heating and this is one of the major applications where such systems used. This is where heating, ventilation and air conditioning comes in. In the United States alone, it makes up for 25 percent of energy consumption. The use of solar heating systems will serve as a great help in saving money as well as save in offsetting the use of fossil-fuel-generated energy. In space heating, solar air heat collectors are used which have two types.

The first type is the glazed solar collector and this works primarily for space heating. The air is heated and recirculated all throughout the building through the solar air panel. Such solar heating system works if and only if it is warmer than the building’s or home’s room temperature. It also requires 2 infiltrations in the building for the whole system to work properly.

The unglazed solar collectors on the other hand are for pre-heating of industrial, commercial and institutional make-up ventilation. This is best for buildings that have high-ventilation volume needs. As a result, it turns walls or sections of it into low cost at the same time high-performance transpired solar collectors. In order to do this, a painted and holes metal that serves as a wall exterior. There is a thermal boundary layer of air which is 1mm thick outside the absorber. The conduction happens from the absorber surface and down to the thermal boundary layer. The layer of air is then strained to the perforations which is led to the absorber plate into the ventilation system of the building.

solar heating thermal systemsAnother solar heating system is called solar roof ponds. It was invented in the 1960’s by Harold Hay. This is a system that includes heating and cooling. It is made of the roof-mounted water bladder that has a movable insulating cover. This system is able to control heat exchange between the inside and the outside surroundings. Controlling can be done through the simple process of covering the bladder during the night and uncovering it during the day. Uncovering the bladder allows it to store heat that can be used during nighttime and the opposite is done to cool the building during the daytime.

Utilizing the sun’s power to heating or cooling advantage is an practical way to save on electricity bills. Aside from the savings, it also makes it easier for people to help the environment since they do not use fossil-fuel-generated electricity. It is like hitting two birds with one stone. This is what solar heating

Using Passive Solar Energy in Industry

Using passive solar energy in industry utilizes sunlight to provide heating and cooling of water and air with out the use of any mechanical aid. Once the system is in place it is extremely efficient and relatively maintenance free. However, the success of a passive system is largely based on the location of the sun relative to your facility and the design of your building. The altitude of the sun at particular times of the day and year as well as the geographical location of your site is each critically important variable in maximizing the performance of passive solar energy systems. An example of the merging of the environment with the design of your facility would be the use of a solarium that can provide critical floor space as well as house energy containment units. In a lobby situation energy can be contained in aesthetically pleasing vessels such as rock walls; whereas a clear ceiling warehouse may be better fitted with less attractive steel or polymer containers. Other systems put function over form and look a lot like the large black solar-electric panels fitted to roofs of buildings and homes.

 

Using Passive Solar Energy in Industry: popular uses

Passive solar energy systems can be utilized to efficiently supply energy for heating and cooling your facility. Heat can be collected and stored throughout the day and then ventilated through your facility at nigh when the temperature drops. Similarly, water can be heated throughout the day and contained in storage units until it is called upon for use in your facility. In fact passive solar water heaters generate more power than those used for generating electricity. Passive systems store the suns heat directly and do waste the energy required to convert light into electricity.

Using Passive Solar Energy in Industry: super efficient

Because there is no energy lost, passive systems are an excellent way to capture the solar energy needed for heating and cooling water and air. However, it is often necessary to couple the cooling aspect of a passive system with a dehumidification system to remove the associated moisture in the air if used for the ambient climate of work areas. Machines generally can not affected but humans are generally more comfortable in lower humidity environments. For general climate control, passive systems will require at least 1/3 of the total footprint of your facility; but may require much more for industrial applications.

Passive solar systems are best if put in place during the design phase of your facility. Systems that are added to existing structures are generally more expensive to install and less efficient. Using passive solar energy in industry is an effective way to harness the sun’s energy for climate control, water heating, and industrial applications.

Taiwan’s Big Marine Energy Announcement

Taiwan, formerly known as Formosa, a Portuguese term that means “beautiful island” is indeed a fine island state. It is located in the southern coast of China 180 degrees south of China. The East China Sea is located on the north side of Taiwan, the Philippine Sea at the east, Luzon Strait at the south and the South China Sea at the southwest. With the vast waters surrounding the beautiful island, the Ministry of Economic Affairs’ Bureau of Energy has seen a great potential for the surrounding waters as a source of renewable energy and they were proud to share this good news to everyone.

The country of Taiwan, though small is suffering from heavy pollution because of the high population density and the great number of factories present here. Some of these come from their coal and petroleum deposits, which are a great part of their energy resources. However, Taiwan is now turning to greener ways and renewable energy. They have tapped into using solar and wind power as part of their efforts to become more environment-friendly. They are now utilizing the abundance of wind energy resources available which resulted in wind farms found on and off-shore. Although the limited land area for wind farms makes the off-shore type more favorable.

If there was another energy resource that is abundant in Taiwan, aside from wind power, it is the surrounding waters. Taiwan has now initiated the gradual energy transition. The island state now is considering going the way towards the renewable energy sources because it has been heavily reliant on fossil fuel for energy. Taiwan has been predominantly sensitive to energy price fluctuations due to the fact that roughly all the fossil fuel they are using are all imported.

In relation to this, the Ministry of Economic Affair’s Bureau of Energy held an international symposium on marine energy in Tapei last April 22, 2011. According to the Bureau of Energy officials, the seminar invited local and foreign experts who have shed some light onto the harnessing of the power of ocean tides, waves, currents, and temperature differences by sharing their ideas and even experiences on the matter. The Bureau of Energy aims to produce or generate some 200 megawatts of electricity from the energy resources through the available marine energy resources by 2025. The Taiwanese government is offering its full support on the potential energy that can be utilized from the surrounding waters of the island state.

Aside from the symposium held, Taiwan is also launched a 2,700-ton ocean research vessel last June 13 of the same year the seminar was held. It was launched in the southern port of Kaohshiung as part of the continuous efforts of the island state to open a new chapter in their ocean research. The vessel is called Ocean Research V and it is the largest to be launched by the nation. It will play a great and crucial role in studying the weather, ocean floor exploration and alternative energy research according to Yang Yih from the Taiwan Ocean Research Institute.

Ocean Research V is a vessel which was built robustly in order to withstand up to 40 knots of waves that are results of strong winds. It was designed to stay on the seas for 60 days. The characteristic of the vessel of strong resistance allows the research to continue even if it was winter season. With the initiatives that the whole nation has put in it, the vessel has underwater robots that are capable of diving deep. The robots can go as deep as 3,000 meters underwater.

The vessel is tasked to unlock the potential for energy offered by the waters around the island state. It will also be tasked to research on earthquakes and tsunamis by drilling the seabed. The whole research effort does not only involve the Ocean Research V, there are three other ships that will be alongside the mission to research on these alternative energy resources. There is Ocean Research I, II and III that will undertake tasks and projects in unison with the furthering of the competences of Taiwan’s marine science and technology.

After the successful launch of the Ocean Research V, Taiwan Bureau of Energy has announced last August 22 that they are now aiming to have a renewable energy capacity of 8,450 MW in 2025. It will be equivalent to 15 percent of the total power they have. Taiwan’s oceans naturally has a power generating potential of 10GW this is why it will not be hard to harness the 15 percent which will roughly be equal to 200MW. The Bureau of Energy has said that they are looking into the rich energy sources such as tidal, wave and even ocean thermal energy conversion or OTEC.

Currently with the research and development on the way, the island state is looking into the use of the ocean thermal energy conversion. This energy resource will be appropriate in the eastern Taiwan regions. There are open seas that surround the areas like Hualien and Taitung in this region. In using the OTEC or ocean thermal energy conversion, there is a need to have a 20 degrees Celsius or 68 degrees Fahrenheit difference in the top warm layer from the deep cold layer of water. The waters in this region in Taiwan fit such required condition because the top layer and the layer 1,000 meters below surface can reach 20 degrees Celsius.

Tidal power on one end is suited for the northeast region of Taiwan. This area has open seas that have tides that reach up to 10kW/m. The use of the waters around the island state does not end there because the island state is looking to maximize the available regions where water is available. They are also looking into using wave power on the waterways available at the eastern and western regions. On the eastern part, the Kuroshio Current is being considered. On the western part, the waterway around the small isles called Penghu islands.

Taiwan, although a small island nation is now looking into the available renewable sources of energy that will not only lessen the volume of pollution that they have but will also help their economy. It is wise to use different approaches of harnessing the potential energy being offered by the surrounding waters. This is just a great example on how investing in green energy will not only help boost the economy but will also help prevent further destruction of the environment. In order to complete the success of Taiwan’s efforts, their studies should also include the right way of harnessing energy from the ocean otherwise all the great steps they have taken will be no good. As rich as it is, the ocean has a lot of uses as people can imagine and this is just what Taiwan’s announcement has made known to many.

Ocean Thermal Energy Conversion’s Green Energy Attributes

The ocean is considered to be one of the most abundant places on earth because of the underwater life it has. Not only does it house a wide variety of fish but it is also a source of energy, how so? Water naturally takes time to warm up as well as cool down. With such characteristic, man has come up with the ocean thermal energy conversion as a source of a renewable green energy. Many experts believe that when this is perfected, it is an equally competitive source of a great amount of electrical power. In relation to this, it is wise to look closer into what are the things that are involved in ocean thermal energy conversion along with the other facts connected to it.

The ocean thermal energy conversion, also known as OTEC was founded on the principle of heat stored in ocean waters. Since the earth’s oceans vary in depth, the temperature of the water also differs. The top layer of the ocean is normally warmer than that of the water found in the middle and near the bottom. OTEC works best when there is at least 20 degrees Celsius or 36 degrees Fahrenheit difference in the warm top layer and cold deep ocean water. This temperature difference is often found in tropical areas. It is said that these requirements are met by the areas in between the tropics of Capricorn and Cancer.

It was Jacques Arsene d’Arsonval, a French physicist suggested that the thermal energy of the ocean can be tapped. However, in the year 1930, it is his student Georges Claude who actually built an OTEC plant in Cuba. The plant produced 22 kilowatts of electricity through the use of a low-pressure turbine. In the year 1935, George Claude again made a plant on board a 10,000-ton cargo vessel anchored to the coast of Brazil. However, this attempt was unsuccessful for the plant was destroyed by the waves and weather before it could even function. 21 years after, French physicists designed 3 Megawatt plant for use in the Abidjan, Ivory Coast in West Africa. This endeavour, too, was unsuccessful because of economic reasons and expensive costs.

The United States became involved in 1974 through the Natural Energy Laboratory of Hawaii Authority at Keahole Point on the Kona coast of Hawaii. It was said that Hawaii is the perfect place to build an OTEC plant for it has warm surface and cold deep waters. As a result, it became the OTEC leading test facility.

The first attempts to build a bigger OTEC facility were unsuccessful and there were additional studies that were made. In the year 1970, Japan was able to build a 100kW closed-cycle OTEC plant on Nauru Island. This was brought about by the Tokyo Electric Power Company and was fully operational by the year 1981. It was producing about 120 kW of electricity. 90 kW was used to sustain the OTEC plant and the electricity left was used by other places like schools. This breakthrough did set the standards and a world record which was sent to a real power grid.

Ocean thermal energy conversion involves three kinds of cycles that encompass the use of warm and cold water. The first type of cycle is the closed kind. This cycle uses low-boiling point fluids like ammonia, this then turns the turbines and in order to generate electricity. In this cycle, the warm ocean water is pumped through a heat exchanger to vaporize the fluid. The cold water is then pumped through a second heat exchanger which condenses the vapor to be recycled through the system.

The second cycle which is the open type uses the warm surface water to produce electricity. The warm ocean water is placed in a low-pressure container that causes it to boil. As the water boils, the turbines which are connected to the generator are turned. The cold water on the other hand, is used in condensation of the steam that has rid of its salts and other contaminants. This procedure is called desalination and it produces fresh potable water that is suitable for drinking and other uses.

Hybrid is the third type of cycle and from the name alone it is the combination of the open and the closed cycles. In the hybrid cycle the warm surface ocean water enters a vacuum chamber which is flash-evaporated. After which the vapor is used to vaporize the ammonia just like in the closed cycle and this turns the turbines to generate electricity. The steam then condenses in the heat exchanger and results to desalinated water just like in the open cycle.

Ocean thermal energy conversion together with the process of electrolysis can also produce enough hydrogen. Electrolysis is using direct electric current to facilitate a non-spontaneous chemical reaction. The generation of steam along with supplementary electrolyte compounds for efficiency improvement is a qualified medium for hydrogen production. Hydrogen produced can be used as fuel just like the other energy sources.

The ocean thermal energy conversion is not only used to produce electricity but it is also used for the purpose of air conditioning. The OTEC system which makes cold water available makes it possible for large area cooling in properties or projects near the plant. The cold water which has a temperature of 5 degrees Celsius or 41 degrees Fahrenheit is available to cool coils for building air conditioning. This is beneficial for businesses that need air conditioning for it only costs 5 to 10 cents per kilowatt-hour. This can help business owners to save in $200,000-$400,000 in energy bills. In fact, international hotels and businesses in Bora Bora like InterContinental and Thalasso Spa uses the OTEC system for air conditioning.

Another use for the ocean thermal energy conversion is agricultural chilled-soil. This is important for plants that grew in temperate weathers to survive in the subtropics. This happens when the cold-ocean water flows through underground pipes and chill the soil around the pipe. Dr. John P. Craven, Dr. Jack Davidson and Richard Bailey of the Natural Energy Laboratory of Hawaii Authority (NELHA) have patented this process. They have demonstrated that plants that could not normally survive in Keahole Point or in Hawaii did grow in the research facility.

Aside from this, the aquaculture is also benefited. High concentrations of needed nutrients are depleted in the surface waters because of biological consumption. With the OTEC system, the natural upsurge is simulated which is essential for the fertilization and sustaining of the marine ecosystems. Just like the idea of the chilled-agricultural soil, non-native water species can be cultivated in OTEC pools. Some of these species are salmon, lobsters, clams, trout, oysters and abalone. Not only does the ocean thermal energy conversion allow the great fresh seafood to be available in the market but it also helps in refrigeration.

However, the ocean thermal energy conversion also has its drawbacks. One of these is dissolved gasses. This happens in the intake pipe when the cold water rises and the pressures reduce at the point where the gas arises. Another disadvantage is called microbial fouling; a layer of this can be as thick as 25 to 50 centimeters. The thickness of it affects the performance of the heat exchangers adversely by almost 50 percent. This needs continuous removal in order to keep the performance of the heat exchangers at their peak. It was also found out that the sealing is hard and may cause a downside. The evaporator, turbine and the condenser needs to have a fractional vacuum of 3- 1 percent atmospheric pressure. The OTEC system must be prudently sealed in order to keep the operation from ceasing.

These are the components, advantages and the drawbacks that is present in the ocean thermal energy conversion. It is one of the green energy sources that are not yet used widely. From the year of 1880, there had been developments in this energy source. With the continuous study and dynamic technology, great possibilities of improvements on the OTEC process can be achieved in the future. Not only does it present many advantages but it also uses the natural power present in the ocean. Ocean thermal energy is indeed a green energy.

Tidal Power Plants an Ecologically Safe Investment

Things to know before you invest in Tidal Power Plants. The tides are the result of the gravitational attraction between the earth and the moon. The strength of a wave is greatly dependent on the earth-moon system. The tidal power is extracted from the strength of the tides resulting from the variation of the gravitational pull between these celestial bodies. The natural strength of these tides is a great source of energy. When the tidal power is harnessed it becomes a great source of sustainable energy.

Before the tidal power is used to produce energy there are requirements that must be met. Since there are consistent high and low tides in all coastal areas these must meet the five meter or sixteen feet requirement. However, not all coastal areas have the range of this tidal magnitude. There are only 40 coastal sites on earth where such tidal power is present.

Components Of Tidal Power Plants

In starting the tidal energy harnessing of a tidal power plant has three main parts. The barrage or dam has gates and turbines installed. It forces the water through the turbines that activates the generator. A tidal fence is also part of the plant. The tidal fence looks like a baffle gate which spins in the event of strong current on the coast. The last part of the power plant is the tidal turbines which are located underwater, arranged in rows just like in wind farms. The operation of the barrage is inexpensive but the construction of it is very costly and time consuming. The generation of power in the form of electricity happens when the barrage forces the tides into the turbines. The water turns the turbines when it goes in and out of the tunnels in the barrage and the activates generator.

Ecological Impact of Tidal Power Plant Investments

The energy generated by the tidal power plant can be compared that of a dam. That being said the ecological impact is much smaller than that of a dam because tidal power plants harness the power of the tides without interrupting the natural flow of the tides. This is good not only for a piece of mind but it also safeguards your investment money from future regulations and unexpected expenses associated with leaving a large economical footprint. What’s good for mother nature is good for your wallet. An example of this is the investors the Shoreham nuclear power plant in New York that gobbled up billions of investment dollars and never even generate 1 watt of electricity. Another example could be the diminishing returns that coal and oil plants are facing mostly due to government regulations on emission output levels.

Solar Electricity: Green Energy Powering Off-Grid Home Lighting

Just like the tree which has many uses, the sun’s power, also known as solar energy can be used in various ways. The sun is a natural source of light during the daytime; however, people use artificial lighting powered by electricity at night to live comfortably. The availability of light at night does not only allow people to do their activities but it also keeps them safe from any potential threat of burglary or home intrusion. However, the sun’s energy needs to be harvested and converted into solar electricity to power electrical equipment and lighting fixtures. This is called the off-grid energy which is cheap and environment-friendly. In order to understand this technology we are going to look into the processes and factors involved in it.

In order to use solar energy as electricity, it must undergo the Photovoltaic system. Photovoltaic technology or PV uses an individual or sets of solar panels. The solar panels then convert the solar energy into electricity. A PV cell is made of more than two thin layers of semi-conducting materials. The common material used is silicon and when it is exposed to sunlight will generate electrical charges. When the electrical charges are produced, metal conductors draw these away as direct current or DC. Note that there is a need for several cells for the electrical yield by a single cell is just small. The whole set of multiple cells are connected and is cased behind a glass to form a module. A number of modules can be connected to get the desired amount of electricity.

One of the most common uses of solar electricity is the off-grid lighting technology for it is inexpensive and is environment-friendly. It is a small investment that home owners that can benefit the whole household. The off-grid lighting technology allows homes to have three light qualities. These are ambient, general and task lighting. All these three are made possible by the cheap solar electricity.

Ambient lighting provides a minimum amount of illumination for people to move around living spaces and see each other. This type of illumination is also known as the dim light. This is usually the type of lighting candles, wick lamps and hurricane lamps give off. In households, this is useful in sitting rooms as well as children’s quarters. This helps children who are usually afraid of the dark; they get to sleep and rest better.

General lighting offers enough illumination for seeing objects and for reading. With the right amount of illumination that general lighting offers, the household members will be able to do their chores. Children will be able to study and do their homework. Parents on the other hand can do the cooking and washing of dishes. This type of illumination is the same kind that pressure lamps, LPG lamps and incandescent bulbs provide. This offers security to most households because studies show that when there is enough light inside and outside the house at night, burglars will not risk breaking in for the last thing they would want is a confrontation between them and the home owner.

The third type of illumination that off-grid lighting can provide is the task type. The task lighting provides bright illumination for specialty for viewing details closely. This is important for home owners who do detailed jobs such as engineers and architects. The task lighting allows architects to make and review floor plans and blueprints carefully, not missing important details. This type of lighting is also given off by Halogen, fluorescent, cluster led.

The most famous types of lighting that uses the solar electricity are LEDs and CFLs. LEDs or light emitting diodes when powered by solar electricity will not only deliver cheap lighting but will also provide bright lights that can give off general or task lighting. The CFLs or compact fluorescent lamps also offer both general and task lighting. These sets of combinations are really affordable that low-income people can take advantage of them. People will not also think of high electric bills to pay since solar electricity is used.

Another advantage that off-grid lighting has in relation to solar electricity is that it seemingly comes with a stand-alone generator without the batteries. The electric charges produced are economically viable for hours. Having the PV installed in homes will also offer another reason for practicality. The whole PV does not come with moving parts, thus there is no need for meticulous maintenance. The whole idea of maintenance is related to expenses. Since the PV system does not require maintenance, then there will be less expenses on the home owner’s part.

The green energy, solar power is truly useful in many ways. It provides many functions to homes such as heating, and this time lighting. Unlike regular electric-powered lights, the off-grid lighting technology derived from solar energy does not emit harmful greenhouse gasses and is inexpensive as a whole. This is a benefit of sustainability that green energy offers. Hearing the off-grid lighting technology may seem intimidating but in actuality it is beneficial for many homes.
