Do We Need To Find Alternative Sources of Energy?

Is there really a need to find alternative sources of energy? I believe there is. The problem we face is figuring out how to tap into the renewable, natural resources we have. The pollution from using fossil fuels and from nuclear waste is going to have consequences to us and to our environment. Just what alternative energy sources are available?


Solar Energy

Solar energy is just energy from the sun that is converted into electricity using a process called photo-voltaics. Solar power has been used for quite some time and can give us electricity for homes and buildings. It can also be used as fuel for vehicles, for solar cookers, in metal smelting, and to make industrial chemicals.


Hydroelectricity

Hydroelectricity is the most commonly used source of alternative energy. This type of power is made by utilizing the gravitational force of water falling from a high place. Here's the good news; hydroelectric plants do not create toxic by-products and don't emit many greenhouse gases. Dams can be expensive to build and maintain, but the benefits of a hydro-electric plant outweigh the cost in the long run.

Wind Energy

Energy that comes from the wind is renewed each time you use it and won't cost you much at all . Wind power can be used in agriculture to pump water or grind grain. We can harness the power of the wind to run our homes and the various 'gadgets' we seem to have so many of.


Geothermal power

Heat from below the earth's surface produces geothermal power. From an economic standpoint, this form of energy is more feasible than using fossil fuels that have rising costs. One large geothermal plant could power a whole community. Geothermal plants run a lot cleaner and don't release a lot of poisonous gases into our air.

These are the more common and environmentally friendly alternative energy sources. I think we need to explore these options and implement them as much as we can.
