According to a report in the Times, the invention, known as ‘Searaser’, is designed to pump water hundreds of feet above sea level from where it can gush [...]
A reddish microbe found on the inside of a tree at a secret location in the rain forests of northern Patagonia could unlock the biofuel of the future, say scientists.
Its potential is so startling that the discoverers have coined the term “myco-diesel” — a derivation of the word for fungus — to describe [...]
When you think about the natural things around us a couple of things come to mind. First, you have the sun that continues to shine brightly in the sky day after day. It gives off a great deal of heat which can be converted into energy. The sun shines brightly some days and then is [...]

.There is also power found in water and that process is referred to as hydropower. It can create much more energy at one time than either solar power or wind power. This is due to the fact that water is so dense.
Therefore it only takes a little bit of water to create [...]
The use of renewable energy is extremely important for the future development of our globe.
As energy demands increase, we cannot afford to increase the capacity of fossil fuel usage. The reserves of fossil fuels are decreasing on a constant basis, and no matter how slow this process may be, we need to look into alternative [...]
Blue energy, osmotic power plant or salinity gradient power is the energy retrieved from the difference in the salt concentration between seawater and river water. Two practical methods for this are Reverse Electrodialysis , or Pressure Retarded Osmosis .
Both processes rely on osmosis with ion specific membranes. The key waste product is brackish water. This [...]
Definition:
Electrical energy generated by harnessing the power of moving – but not necessarily falling – water is referred to as hydroelectric power.
Hydro electricity is another term for power generated by harnessing the power of moving water. Not necessarily falling water, just moving water. There are many famous such generating stations in the world, not the [...]
Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. The process is widely used to treat wastewater sludges and organic wastes because it provides volume and mass reduction of the input material. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill [...]
British farmers can meet the nation’s demand for both food and fuel crops, argues Peter Kendall, president of the National Farmers’ Union. In this week’s Green Room, he says UK agriculture already has enough capacity to fill fuel tanks and dining tables.

The sun is a very powerful source of energy which powers natural cycles on earth like wind, water flow and plant growth.. Solar power is the technology of obtaining energy from the sun. There are three approaches to gain maximum benefit of solar energy in our buildings.
Passive Solar
Passive solar technologies convert sunlight into usable heat [...]
Renewable energy is the past Cinderalla now invited to the ball, and the rapid expansion in renewable energy will be, and needs to be, massive in order to help alleviate the worst effects of global climate change.
There are many sources of renewable energy. Some are obvious, such as biofuels made from vegetable oil crops already [...]
Solar homes. Many people talk about them, although few in the U.S. do more than talk. They are said to reduce utility bills. Some say a solar home cuts utility bills drastically. Some are able to sell excess power back to the power grid. Savings are not automatic, however. Steps must be taken to make [...]
One of the fastest growing sectors of renewable energy resource development is the wide and varied field of Geothermal Heating. No matter the type you choose to match your needs and location, a geothermal installation can be made completely sustainable and is very scaleable. It is likely that the future of geothermal energy will find [...]

Conventional Water Heaters Use Energy:
According to mechanical engineers at the University of Wisconsin’s Solar Energy Laboratory, an average four-person household with an electric water heater needs about 6,400 kilowatt hours of electricity per year to heat their water. Assuming the electricity is generated by a typical power plant with an efficiency of around 30 percent, [...]
Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate [...]
Solar thermal energy is a technology for harnessing solar power for practical applications from solar heating to electrical power generation. Solar thermal collectors, such as solar hot water panels, are commonly used to generate solar hot water for domestic and light industrial applications. Solar thermal energy is used in architecture and building design to control [...]
Wind power in the United States is a growing industry. As of January 2007 the United States wind power capacity exceeded 11,600 MW which is enough to serve three million average households.
The largest wind farms operating in the U.S. are: Horse Hollow Wind Energy Center, TX (736 MW), FPL Energy; Maple Ridge Wind Farm, [...]
Solar photovolaics (PV) have undergone a remarkable evolution, really a transformation, since the beginning of the industry in the 1960s. Initially solar was so expensive — well over $100 per kilowatt hour — that only super-high value or remote applications, such as satellite and spacecraft missions, could be justified.
Following the OPEC embargoes of the [...]
Geothermal energy is energy obtained by tapping the heat of the earth itself, usually from kilometers deep into the Earth’s crust. It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from radioactive decay of elements like uranium and thorium [...]
Solar Energy is nothing but Solar Power collected from SUN LIGHT (The only source of energy for every living creature of the world)

Water power can be simple called as Hydropower.
Energy in water (in the form of motive energy or temperature differences) can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy.
There are many forms [...]
Wind power is the conversion of wind energy into more useful forms, such as electricity, using wind turbines. At the end of 2006, worldwide capacity of wind-powered generators was 74,223 megawatts; although it currently produces just over 1% of world-wide electricity use, it accounts for approximately 20% of electricity use in Denmark, 9% in Spain, [...]
Renewable energy utilizes natural resources such as sunlight, wind, tides and geothermal heat, which are naturally replenished. Renewable energy technologies range from solar power, wind power, and hydroelectricity to biomass and biofuels for transportation. About 13 percent of primary energy comes from renewables, with most of this coming from traditional biomass like wood-burning. Hydropower is [...]
