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.

February 22 Green Energy News

February 22 Green Energy News
HEADLINE NEWS:

* Electric car sales (including plug-in hybrid electric cars) in the UK surged over 300% in 2014, as compared year-on-year against 2013, according to the most recent figures from the European Automobile Manufacturers Association. EV sales in the UK rose from just 3,833 units in 2013 to 15,361 units in 2014. [CleanTechnica]

* The oil and gas industry sponsors and spins research to shape the scientific debate over horizontal hydraulic fracturing, or fracking. That's the conclusion of analysis by the non-partisan group, Public Accountability Initiative, of more than 130 documents distributed to policymakers by industry representatives. [Huffington Post]

* A broad political coalition, from liberal environmentalists to tea-party conservatives, has banded together in Florida to press for something that ironically is in short supply in the Sunshine State: solar power. The group launched a campaign to place a pro-solar initiative on the state's 2016 ballot. [Fox News]

* Illinois legislators introduced a bill to spur new growth in the clean energy industry, creating an estimated 32,000 jobs annually, once proposed clean energy standards are implemented. Illinois already has 100,000 clean energy jobs. The bill is endorsed by the recently-formed Illinois Clean Jobs Coalition. [Energy Collective]

* The city of Munich is claiming that a giant wind farm being built off the coast of North Wales will contribute to its renewable energy targets, after it acquired a lb660 million stake in the scheme. This leaves the UK with the question of how it can apply power from Gwynt y M^or to its own renewable targets. [Business Green]
