Introduction
Solar energy is a lot better for the environment so researchers are constantly working on ways to harness sunlight.
Why do we use fossil fuels and not solar energy?
Fossil fuels are much cheaper than solar energy, but unlike fossil fuels solar energy is a renewable energy source. A renewable energy source comes from a natural ongoing process that will continue into the forseeably future.
How can we collect solar power?
We can collect solar energy with thermal collectors. Thermal collectors use sunlight to warm water which is used to heat buildings.
What are photovoltaic cells?
Photovoltaic cells convert solar power straight into electricity. They are the dark panels you see on solar powered devices like calculators and satellites.
What are the drawbacks?
Solar panels only turn 15-20% of sunlight into electricity. That's enough to power a calculator but for a house you would pretty much need to cover the whole roof in panels! The sun isn't always shining so you wouldn't be able to get energy all the time unless you stored it which costs a lot of money. Solar panels are so expensive.
Conclusion
I think we shouldn't use solar energy because it costs around $6,000 and when the sun's not out we usually want to use something electric but thats when there is no energy.
