Question

What are the main advantages of using solar and geothermal energy???

Answer 1

Less pollution

Theoretically, the source of energy input/material input in unlimited, whereas carbon based fuels are in limited supply, and are rising in cost.

Promotes independence from foreign energy.

The energy potential has yet to be reached, both technologies are in their infancy.

Answer 2

It is renewable and "supposedly" less population.

There are two forms of solar energy.  1.  Solar electric.  It is clean but the solar panels only work well up to about 20 years.  The manufacture process of the Solar panels also generate tons of pollution due to the chemical content.

2.  Solar thermal.  This is the ideal form of solar energy as it is more efficient since it uses all the heat and light generated by the sun.  It is also clean but it requires a large area and tons of water.  It generates heat by focusing the sunlight onto a focus spot and heat up water which turns into steam and that powers steam turbine which powers electric generators.  it is like burning ants with your magnifying glasses.

Answer 3

I believe the main advantage of these two technologies is their ability to be localized, and by that I mean wherever you need energy, you can put up a solar panel and you have energy. Doesn't matter how far from the closest power line, they can work most anywhere.

Secondly, speed of installation. Compare the time it takes to get some solar panels up and running on your roof to the time it takes the government to approve a new power generation plant... and you have a powerful energy source. Even if you compare the an industrial solar farm installation to the building of new power plant, the time frames are compressed greatly.

Conclusion: quick and simple and anywhere.

Answer 4

Its expensive to build

But free to use - solar energy

u will get high power of electricity - geo

Answer 5

Iceland produces all of the heat and electricity from geothermal energy.  People have hot and cold water pipes coming into their homes.  There is almost no pollution and it is an abundant and cheap energy source.  They are lucky to be in a part of the planet where magma is close to the surface.  We have some places where this is possible in the US.  Yellowstone is one of them.
