As I look more and more into my topic that I chose for the research assignment I find myself more and more interested in the subject. I think this is because of three different reasons, one being: the sun gives off enough energy to supply the entire earth for 27 years daily(www.altenergy.org) and it creates over 9 million jobs and makes $1 trillion dollars in revenue just in the US annually (www.ases.org/about). Then, the last being due to the fact that solar power is the starting point to all other forms of alternative energy. It causes the changes in temperature that causes wind, it's sunlight allows for biomass products to be produced.(www.altenergy.org) Then, finally it's radiating energy results in warmth on the planet and also that energy can be converted and used for nearly any form of energy that we would ever need as humans.(www.altenergy.org). The other thing that I've noticed throughout looking through more of my sources is that so far I have only found two negatives about it. One being the total amount of sunlight, which is a problem during stormy and cloudy days. Then, the other being the cost of initially putting in the equipment. Both of which seem pretty minuscule compared to the harm that the current mainstream sources of energy is doing to the environment. So to sum up the work since choosing the topic, I feel there is a lot of reputable information and that this subject will really open both my eyes, and others to the subject.

Solar is a good topic. You note that it has limitations in terms of the total amount of power. There are also infrastructure power grid limitations that make it hard to generate solar power in AZ and ship to OH.
ReplyDeleteThese problems tend to suggest that solar alone may not yet be adequate. What then?
