The question that we need to ask is not when we will find an alternitive but when we are going to use what we already have.
I took a Sociology of Transportation class a few terms ago, it was quite enlightening. one of the books that we read was "Children of the Sun; A History of Humanity's Unappeasable Appetite for Energy" by Alfred Crosby. He says "Heat engines and electric power plants burning fossil fuel emit millions of tons of sulfer dioxides, nitrogen oxides and other pollutants into the air."
According to the Center for Desease control (www.cdc.gov) athsma is at an all time high in children and adults and the main cause is Environmental Exposure.
And according to Crosby our electrial usage has increased from 2000 Kilowatt-hours in 1950 to 12,700 in the year 2000.
We already have a viable alternitive, bio diesal, it cost less to make and to use. the United States is the largest purchaser of crude in the world.
We need to find more viable ways to reduce our contamination of the planet. Our Polar Ice Caps are melting. Our tempuratures are rising and people are dying because of it. If we continue at this rate we will not have a planet to leave our children

Energy is required for growth and development. We need energy to fulfill our most basic needs- from producing food to generating heat, energy is required on a daily basis. However, fossil fuels make up 80 percent of the world’s energy consumption, and this is problematic at best. Fossil fuels are unsustainable. They are “formed from the decay of plants and animals over millions of years, [and] our planet has a finite number of deposits.” (EarthTrends) In October of 2006, EarthTrends estimated that at the current consumption rates, about 155 years of coal, 65 years f natural gas, and 40 years of oil were left.
We also have to worry about the effects these fossil fuels are having on our environment. The “emission of carbon dioxide and other ‘greenhouse’ gases from the combustion of these fuels is rapidly warming the planet, altering our climate system, and jeopardizing the well-being of both people and ecosystems. Fossil fuel combustion currently accounts for 61 percent of greenhouse gas emissions.” (EarthTrends)
Despite these disturbing facts, EarthTrends believes that we can reduce our dependence on fossil fuels. Most importantly, we need to “develop fossil fuel energy alternatives, increase energy efficiency, and reduce energy consumption.” (EarthTrends) Various fossil fuel alternatives, such as solar power, hydropower, and biofuels are currently capable of providing sustainable energy. Also, EarthTrends emphasizes the importance of individual actions. Simple things, such as replacing incandescent light bulbs with compact fluorescent lamps or using public transport, help to use much less energy. Even turning off lights and electronics in your homes and offices reduces the amount of energy you consume.
EarthTrends stresses the importance of reducing our reliance on fossil fuels. On a larger scale, it asks countries to consider using alternative forms of energy and to increase energy efficiency by using technology and market mechanisms. It also offers us hope, and reminds each of us that there are simple things we can do to reduce our reliance on fossil fuels.

On October 2nd, President Barack Obama declared October as National Energy Awareness Month. He addresses how energy research and development will help our society on a number of levels, from helping to save the planet to helping to save our economy. While research and development is all good and well, we, as individual Americans, are supposed to be recognizing National Energy Awareness Month by "making clean energy choices that can both rebuild our economy and make it more sustainable". Not all of us are able to replace energy-inefficient appliances, or make other energy efficient installations, but most people could make minor changes that would make for smart energy-saving choices. Here are a few easy ideas from Blackle:
- "Turn off everything not in use: lights, TVs, computers, etc."
- "Activate "sleep" features on computers and office equipment that power down when not in use for a while. Turn off equipment during longer periods of non-use."
- "Replace your five most used light bulbs with compact fluorescent bulbs. These light bulbs use two-thirds less energy and last up to 10 times longer."
- "Take your own reusable bags to do grocery shopping to save the unnecessary production of plastic bags."
- "Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline, it can lower your highway gas mileage 33% and city mileage 5%."
