Whether you use fossil fuels or an alternative form of energy, one of the key components of the process is usually a generator. Without a generator, you cannot produce electrical energy-you can only produce mechanical energy. For example, when flowing water moves a waterwheel, this is mechanical energy. The waterwheel was sometimes used hundred of […]

When people hear the words “nuclear power,” many think of death and disaster, such as what occurred at the Chernobyl plant in Ukraine many years ago. It is true that we produce nuclear power at a great risk-a total meltdown at a nuclear power plant would affect the entire planet-but there are great benefits to […]

As the United States and the rest of the world seeks alternatives to fossil fuels and nuclear energy, one of the most basic and oldest types of energy, wind power, is coming into play once again. Wind energy is a great renewable resource. The technologies to convert wind power into useable forms of electricity and […]

Fossil fuels and nuclear power are hazardous to the environment, producing pollutants and other harmful by-products. One energy source that does not pollute the earth, however, is often overlooked, although its potential is great-the earth itself. The core of the earth is about 4000 degrees Celsius, and harnessing this power would create a heat source […]

Fossil fuels-oil, coal, and natural gas-are running out quickly, and since much of the world’s power depends on these resources, in the next few hundred years this could be a major problem. However, if we aren’t more careful about the way we use these natural resources, we won’t have to worry about that; the world […]

Most supporters of the many alternative energy options available today talk about the greenhouse effect. Cutting down on our use of oil, coal, and natural gas will significantly reduce the greenhouse effect that is a daily part of our lives. However, if you don’t understand this terminology, you probably will not understand the serious consequences […]
