I have an essay due in science about renewable energy. Just like to gather some opinions on these topics, please do contribute, even if its only saying "I agree with so and so" :)
What are some advantages and disadvantages of using:
1) solar cells (photovolitiacs), which use semiconductor materials to convert sunlight into electric current
2) wind turbines
3) biofuels, such as green diesel and lignin
What steps do you think can be taken to increase the use of renewable energy sources? How would these steps help accomplish the goal?
Thanks so much, your opinion helps! As I said, please answer even if you're only agreeing with someone else! I need all the feedback I can get! :)
