The U.S. has huge reserves of cool,
petroleum and natural gas. In 1970 fuels sold for 20-30 cents a gallon. Now prices go over $2.00.The Department of Energy
(DOE) Oversees the development of energy technologies. This includes nuclear fusion research and development. They are developing
new forms of energy and energy conservation to slow the rate of depletion and its effect after it is consumed. (Environmental

Modern civilization depends on natural resources, mineral fuels. Unlike mineral raw materials this resources can all be used
up. At the current rate of fuel use we will run out in one or two centuries. When fuels do run out people may depend on solar
energy to power cars and factories home heating will use nuclear energy uranium, which will last many centuries. Space satellites
already run on solar energy, this will help to jump-start the wide spread use solar energy. At this time scientist are attempting
to combine nuclear energy with hydrogen to produce new types energy. This is already in some motor vehicles. Also, the fumes
of current factories and automobiles pollute the air, killing trees and endangering human health. The fumes are less dangerous
then the fumes in this new mixture.
Petroleum and oil are expected to run out in approximately 200 years. When this
happens the reliance will increase. Currently there is 750 billion tons of coal, 80% of which is in U.S., U.S.S.R., and China.
Fossil fuels are considered non-renewable resources because it takes a million years to create something that we are using
much more rapidly than it is being created. This is also why we are becoming more reliant on clean and renewable resources.
