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.

Solar Powered Windows Paint And Other Innovations

Solar Powered Windows Paint And Other Innovations
New Energy dubbed their own creation the SolarWindow, which is designed for transparent glass in both commercial and residential buildings.

Scientists have been working in agreement with the National Renewable Energy Laboratory (NREL) to create a more efficient prototype, increasing the number of working solar cells that contact the surface area.

Other technologies look to increase the size of the windows and develop less expensive coating materials (the largest window so far is one square foot).

This will all be done through these innovative sprays and films. The University of Texas is working on solar paint that simply sprays onto the surface, while start-ups like Innovalight have engineered a solar ink "tattoo" that can be applied directly to windows.

Recent employment stats show that the private sector is catching up on investment in future solar enterprises. In the meantime, companies with breakthrough technologies have had to rely on the public sector investments to see their ideas through to production.

This is only the same story that has been told for generations: the fossil fuel industry has always relied on the public sector to deliver fuel.

The NREL is an example of an ambitious program to help solar start-ups get up and running, merging private interest with federal support, to help create more green jobs as well as increasingly lower the cost of solar energy.

Raytheon Demonstrates Advanced Microgrid System And Control Capabilities

Raytheon Demonstrates Advanced Microgrid System And Control Capabilities

By WoR Network Editor

Raytheon Company (NYSE: RTN) and its partners, the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), Primus Power, and Advanced Energy (NASDAQ: AEIS) have successfully demonstrated an advanced microgrid system capable of islanded (off-grid) operation using stored and high penetration renewable energy.

The testing effort, conducted at NREL's Energy Systems Integration Facility, incorporated Primus Power's EnergyPod(R) 706kVA powertrain, two AE 100kW solar inverters and Raytheon's Intelligent Power and Energy Management (IPEM) Microgrid Controller. The demonstration proved the ability for an Energy Storage System-driven microgrid with conventional photovoltaic (PV) inverters to achieve 100% PV penetration while retaining the power quality needed...read more
