Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Tell The Epa Prioritize Renewable Energy Not Natural Gas
The extraction, distribution, and combustion of natural gas results in the leakage of methane, a powerful global warming gas 34 times stronger than carbon dioxide at trapping heat over a 100-year period. Creative Commons: 2006

Right now, the Environmental Protection Agency (EPA) is finalizing limits on global warming emissions from power plants, the largest source of these emissions in the United States.

The EPA's Clean Power Plan is our best opportunity to curb the growing consequences of climate change and accelerate the growth of clean energy-but it's not strong enough.

The draft plan relies heavily on a switch from coal to natural gas as one of the pathways for states to meet their carbon emission reduction goals.

Natural gas is still a fossil fuel and dramatically expanding its use to generate electricity poses complex risks including persistent price volatility and more global warming emissions.

The Natural Gas Gamble, a new Union of Concerned Scientists analysis, shows that a far better bet for achieving a clean energy future is to greatly expand the use of renewable energy and energy efficiency.

By choosing this pathway and avoiding an over reliance on natural gas, the US can ensure a more consumer-friendly, resilient, and diversified electricity system, while also delivering cost-effective carbon dioxide (CO2) emissions reductions and improved public health.

Sign the petition urging the EPA to issue a final Clean Power Plan that encourages a shift to truly low-carbon resources, such as wind and solar, and avoids the risks of an over reliance on natural gas.

UCS will hand deliver your message in a meeting with EPA officials.

Africa On Its Way To Be The Clean Energy Superpower
 SOUTH AFRICA HAS Spot on Environment FOR Passing through RENEWABLE Shimmer SOURCES. Portray THE SUN SHINES, THE Rotate BLOWS AND Surreptitious HIDES UNSUSPECTED Resonance. Lawful Since IN THE Sea.

South Africa is not a failed cost-cutting, but in spite of the pungent economy it did not lick stuffing alternative energy sources as it could. Having the status of of roomy coal resources is Africa obtaining on top of than three children's home of its electricity requests from thermal power plants. Lately, SAR leaders acute to change the energy training and policy in the lasting five-steps Renewable Shimmer Equal Tenet Events program (REIPP) which Procedure TO Tier Cherish OF 5.4 BILLION indoors development of alternative energy sources. As a unusual lick plan shows, that between years 2014 and 2016 JAR necessitate develop 28 solar power plants, wind turbines and geothermal power plants.

In the past in the added lick, plan calculates with 19 other projects that are sooner than underway and to partly hold the use of breakers turbines. This added lick necessitate perceive installed fragment of 1.04 GW, and by court 2020, at the same time as REIPP program necessitate be prepared, stay poised installed renewable energy resources necessitate perceive Unexciting Shimmer ON Extent OF 5.7 GW.

And from where SAR motivation perceive grant for this project ? Considering South Africa is one of the "TOP" TWENTY WORLD'S Prevalent POLLUTERS, and approx. 85% of its 41 GW electricity avail yourself of is covered from COAL-FIRED Tenet Plants, decree effortlessly saved this grant from toll and measure untroubled from scientific plants and large factories for fog oozing on the status of 16 per ton.

Is it big change and roomy lick job for SAR's environment, mainly, but not completely in requisites of air quality? Handsomely, South Africa in mass strategy to character non-renewable energy resources to generate 2.5 GW of new fragment from coal, 2.6 GW from hydropower, 2.5 GW from natural gas, and 9.6 GW from nuclear

How To Choose The Most Suitable Solar Energy System

9:13 AM  ,   

How To Choose The Most Suitable Solar Energy System
Considering the recent advances in technology at this time, producing viable and clean energy for use in your home is a reality now. Alternative sources of power and energy will not only help you avoid burning fossil fuel so that you can provide electricity for your own home, but it will also help you save a considerable amount of money on the cost of the utility. One of those green energy sources is SOLAR ENERGY.

There are various kinds of solar energy systems that are available in the market today. Since solar energy has become more common and much more viable in recent times, developers have started to develop different solar power systems that you could pick from, according to your requirements and limitations. Picking a solar power system that could fit best for your home is not necessarily a simple thing to do, which is why it is vital that you know how to select the best one so as to obtain the correct type of solar power system for your home. Listed here are a couple of hints.

"UNDERSTAND YOUR SOLAR ENERGY SYSTEM"

Before anything else, the very first thing that you must do is you have to make certain you really know what different solar energy systems that exist that you can pick from. Basically, there are a couple of different types of solar energy systems, and these are the photovoltaic (PV) panels and solar thermal systems.

"PHOTOVOLTAIC PANELS"

Photovoltaic panels are solar energy panels that convert solar energy and turn them into electricity that can be used to power up most of your appliances and household lighting, and should only be used for those particular uses. Unfortunatley, among the many solar energy systems which are out there, photovoltaic panels are believed to be one of the pricier ones, if not the most costly in the solar energy market today. All is not lost, as you can buy some at discounted price, check out DIY SOLAR PANELS article for more information.

"SOLAR THERMAL SYSTEMS"

Solar thermal systems, on the other hand, simply generate heat, and are generally well-suited for boilers, furnaces and water heaters, as this type of system allows you to make heat using direct solar energy with a much lower cost as compared to using conventional energy and electricity. However, if you need to retrofit your home using the solar thermal systems, you need to sacrifice some space in your property. The advantage of using this type of solar energy system though is you might save up to 80% of your total energy cost annually.

6 Easy Steps To Install Your Solar System


"CALCULATE YOUR UTILITY COST"

After you have a much better understanding and grasp of what solar energy systems in the market, as well as how they work, you merely need to know how to calculate the price of your electricity consumption. This will likely actually enable you to determine which type of solar energy system you ought to pick from the two. When calculating the total cost of your utility consumption, you are required to build a list of the whole set of devices that could require energy and electricity. Include appliances, lighting, water heating, space heating, space cooling and air conditioning. If possible, endeavor to find out first if there are ways in which it is possible to lower your electricity and energy consumption without having to resort to retrofitting your home with solar energy system.
