With all the talk regarding solar energy for many years its time has finally come. The gradual invitable delpletion of natural resources has made alternative sources an absolute must. It's now a matter of time and we'll determine the eventual new leader. Much expensise and resources is now being spent to find the best natural resource such as solar energy.
While many potential sources are possible, research into all the avenues will eventually surface with the most viable option for our use. Presently we are using a number of various resources to create heat, electricity and desalination of seawater. Renewable energy has the sun as it's primary source which is not depletable. Approxiametly 30% of our enery resources come from the sun.
Most of our enconomic resources and time are spend developing our resources in the area's of wind power, water power, solar energy, biofuel, liquid biofuel, solid biomass and geothermal. Naturally these all have their pro's and cons. The biggest concern is pollution that comes directly the materials, industrial processes and construction equipment used to create them. The side effects can be pollution and waste that will impact our environment.
We also we need to consider other key issues of environmental impacts, aesthetics and habitat hazards, land usage, proximity to demand, availability, reliability, longevity along with energy input verses output. Other possibilities such as fossil fuels and nuclear power have their own positive and negatives and are not as viable. The resources for our use are many, the challenge is not if we have alternates to use but which ones and in what order.
The U.S. currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally-damaging to retrieve. In contrast, renewable energy resources — such as wind and solar energy — are constantly replenished and will never run out.
Renewable energy is important because of the benefits it provides. It is believed that the major element in the learning and discovery process definitely will be and is solar energy.
