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.

Why Is There No National Energy Policy

Why Is There No National Energy Policy
There is no national energy policy because there is no public will for one. Sure, blame Congress or President Bush or the oil companies, but we are the problem. Part of the reason is that life remains okay. -Gasoline now costs 4/gallon, and people complain, but Europeans pay twice this price, and Norwegians get by at an equivalent of more than 10/gallon. The various White House administrations and the Congress never treated energy as a high priority. Sure, lobbyists were very effective, but the fact of the matter is that the populace really did not care that much. Neither did we express much concern for global warming. We get what we deserve.-We have our priorities all wrong, and do nothing about it. For example, EACH NASA space shot is said to cost about a billion dollars. This is more than the annual Department of Energy renewable energy budget.-Each B-2 Stealth bomber sells for one billion dollars...no, make that 2 billion, including all development costs. A B-2 weighs 2.3 million troy ounces, which, if constructed of pure gold, would still cost 2 billion. Of course, it wouldn't be able to fly, but want more? -The U.S. Navy will outlay 160 million/year to man each Nimitz class aircraft carrier, and when the George Bush is christened (no joke, but this named for #41, H.W.) this year, there will be ten of them. The George W. Bush direct solar energy request is about half what it will cost to OPERATE ONE nuclear carrier! And we have ten of them...with no major enemy today!-The American public readily accepts this absurdity. Where are the priorities? What can you do about this? You can start by reading SIMPLE SOLUTIONS for Planet Earth (http://simplesolutionsbook1.com/) and SIMPLE SOLUTIONS for Humanity (http://simplesolutionsbook2.com/). -The world needs to spend not a few billion, but a trillion dollars over the next few years to minimize the crunch of Peak Oil and Global Warming. Remember, the Iraq War is said to have cost 2 trillion, so just one trillion should be simple. How? Tomorrow a proposal to our 44th POTUS (President of the United States). Also, Go Green! Details will be provided from Monday.-The price of oil for the week inched up to 127.35/barrel. Did I say we spend more than a billion dollars a day for gasoline?-
