The Economics of Alternative
Energy
All forms of alternative energy are always affected
economically by oil prices, and the demand of each
alternative energy form. When oil prices are low the
alternative energy becomes less desired because people can
buy oil or gas as their primary energy form without paying
too much. As oil prices increase, forms of power like water
power, solar power, and wind power become good alternatives
to oil and gas because the energy created by water power,
wind power, and solar power is renewable and in the long
term may cost less. An example of this effect was displayed
during the 1970's oil embargo. In the United States, solar
power plants flourished and many new hydroelectric, wind,
and nuclear plants were built.
Other factors also influence the economics of each of the
alternative energy forms discussed at this site. These
factors are discussed below:
Hydro power is affected by something called "load
demand." Load demand is the demand for electricity that
people currently have. If many people need a great amount of
energy, then the hydroelectric plant can sell the
electricity for a lower price per unit. For any alternative
energy form this rule is true because as the demand for
electricity increasesthe price for electricity may decrease
because the businesses can make more money through selling
more quantity. If in a country there is a normal desire for
electricity and other alternative energy forms are already
prominent, then hydro power would not be a good economic
investment. No extra demand means hydro power could not
expect revenue ( or business).
Nuclear power is affected economically when the price of
uranium is too high. In the modern world, uranium has
several uses, one of which is to make nuclear bombs.
Countries stock their nuclear asernal with bombs made of
uranium, and will pay very high prices for the comfort
afforded by possession of nuclear bombs. When a nuclear
power station is first built, the cost is fairly high, but
over time the big cost of nuclear power plants is the waste
management. Because nuclear power plants produce excess
"garbage," it costs a great amount of money to support the
plant because the waste needs to be stored where it will not
affect the environment or mankind.
Solar power suffers from a high intial investment need.
A large amount of money is needed to start an active solar
energy project. As the price for solar cells drops, the
initial investment will also vanish. Solar technology has
always become more affordable when oil prices have been
high. Solar power also suffers in that many parts of the
world are often cloudy and it is more expensive for people
to buy solar cells and only use them a small portion of the
year. As solar cell efficiency increases, it will become
easier for a person who lives in an area of cloudiness to
cheaply use solar power because he will be able to use solar
cells more often.
Wind power has a mixture of costs of those of solar and
nuclear power. Due to the danger of a wind tower falling
over, extra land must be bough near the tower to insure
human safety. Wind power does require a substantial initial
investment. But wind power does not produce waste, so no
great later investment is needed for the life of the wind
power facilities.
