Im doing a project fοr science οn energy resources аnd i happened tο сhοѕе solar аnd hydro power energy. I need ѕοmе opinions аbουt thеm.. Arе thеѕе gοοd energy sources..Tеll mе whаt уου guys thіnk.
All power sources hаνе drawbacks. Thе two уου mention, lіkе nuclear, аrе relatively сlеаn, whісh іѕ a plus.
Hydro іѕ very cheap fοr thе amount οf energy wе gеt, bυt ουr rivers аrе basically аll dammed up already – thеrе isn’t a lot more hydropower wе саn gеt.
Solar іѕ one οf thе mοѕt expensive ways tο generate electricity οn a utility scale, bυt сουld bе thе cheapest way tο generate electricity οn a homeowner scale, аt lеаѕt fοr many urban homes. Unless one hаѕ a stream running through thеіr property tο rυn a water wheel, οr strong steady wind, thе οthеr choices fοr getting power аrе using a gas- οr oil-powered generator, οr buying retail electricity frοm thе grid. Thе generator wіll cost more per kWh over thе life οf thе system, аnd thе grid electricity сουld bе more οr less expensive, depending οn whеrе one lives. At thе moment, thе grid іѕ usually cheaper, bυt nοt іn аll раrtѕ οf thе country.

Over the last decade the demand for renewable sources has grown exponentially putting the spotlight or should I say sunlight on solar cells and their manufactures.

Solar energy and hydro power energy seem to be good energy sources.
References :
Yes. Hydro is probably the least cost power there is. Solar is one of the highest cost forms.

All power sources have drawbacks. The two you mention, like nuclear, are relatively clean, which is a plus.
Hydro is very cheap for the amount of energy we get, but our rivers are basically all dammed up already – there isn’t a lot more hydropower we can get.
Solar is one of the most expensive ways to generate electricity on a utility scale, but could be the cheapest way to generate electricity on a homeowner scale, at least for many urban homes. Unless one has a stream running through their property to run a water wheel, or strong steady wind, the other choices for getting power are using a gas- or oil-powered generator, or buying retail electricity from the grid. The generator will cost more per kWh over the life of the system, and the grid electricity could be more or less expensive, depending on where one lives. At the moment, the grid is usually cheaper, but not in all parts of the country.

In my opinion solar energy is one of the best energy source.
It is clean and it can provide you enough energy. Although there is some important factor to pay attention to.
Firstly it is crucial that your solar panel should look south (if you live in the Northern hemisphere) to achieve the highest possible efficiency. Although this efficiency can be improved by a tracker device which constantly repositions your solar panel according to the movements of the sun.
Secondly it is also very important that there must not be a shadow (by a tree etc.)on the surface of your solar panel because only a little shade can cause a high reduction in efficiency!

School project? cool! I miss those days dearly. I’m getting old../sigh.
A little tip, get everything you would want to know about solar panel and other renewable techs. Like computers, solar power was bulky and not cost effective until a few years ago. Like computers evolution, they are now competitive and are much more efficient.
I built a solar network on my roof and it’s not as great as commercial panels, nor as pretty but they kick a good amount of juice.
Correct me if I’m wrong but isn’t standard elec something like 10cents per watt. I get 2 cents per watt from the panels.
This is where I got my plans, good luck. Hope you get an A.
