needs. So why not use the energy to our homes or our cars?Many scientists have changed forms of
energy called "Green Energy". Green power is the solution to creating a cleaner,sustainable energy
system. Renewable (可重复的)energy—from the sun,wind ,plants and moving water—is a natural way
to meet our energy needs and protect the environment.
Solar (太阳的) energy is a very useful resource today. 80% of the energy we use comes from fossil
fuels (化石燃料) and about 1 % comes from solar energy. Fossil fuels are nonrenewable,that means
that they are used up faster than they could be replaced. Also fossil fuels are limited and cause pollution.
They are the primary cause for air pollution that causes acid rain (酸雨) and global warming. The good
thing about solar energy is that it is renewable because it is always replaced. Also solar energy does not
pollute the environment.
The energy problem is an important problem in the United States. Solar energy can help solve this
problem. But the cost is far too great.
