aware of Renewable Energy
Renewable Energy refers to the power stored in the Earths crust from which it can be renewed at a moment’s notice. This means that the Earth possesses an inexhaustible supply of energy which will last for centuries. Unlike fossil fuel or nuclear energy, Renewable Energy does not pollute the environment. The only byproduct of using Renewable Energy is waste. Many environmental advocates have worked hard to make the public more aware of Renewable Energy, as this form of energy can be the solution to many of the world’s current problems such as limited fossil fuels, dependence on foreign countries for their energy needs, and high levels of greenhouse gas emissions.
One of the oldest forms of renewable energy is Hydroelectricity. Hydroelectricity uses the force of waterfalls and the flow of rivers to generate electricity. With the advent of new technology, more efficient methods of harnessing the power of water are being developed. The Earth’s rivers and streams contain enormous quantities of energy which can be tapped to generate electricity with the use of new dams and turbines.
Another form of renewable energy is Wind
Wind generates electricity through the power of the wind itself, which is generated from thermal collectors. The wind is turned by the engines of windmills to generate electricity which must be stored in batteries for use. Although windmills have been around for centuries, modern usage is limited by the availability of windy areas. Advances are being made to increase the number of windy locations where electricity can be generated.
Another source of renewable energy is geothermal energy. This is produced from the heat of the Earth stored below its surface. Geothermal heat can be accessed through large underground mines where temperatures can reach extreme temperatures. These high temperatures can easily generate electricity generation through geothermal systems.
both cons and pros
The last form of renewable energy sources are hydroelectric power and solar power. These technologies have both cons and pros. Hydroelectric power plants use water to create electricity, but the cost of production tends to be much higher than other forms of renewable energy. Hydroelectric power does, however, create a useful amount of electricity for cities which use it for transportation. The only disadvantage of hydroelectric power is the pollution that can be caused by the disposal of waste into the water. The pollutants from this method are a great environmental concern.
There are a number of sources of renewable energy that can be used together to greatly reduce the dependence on traditional sources of energy. These methods are becoming more popular as environmental concerns become more important to society. There are many ways to capitalize on renewable resources to create environmentally friendly products and services. Biofuels are just one of these ways.
