There are many different ways in which the abundance of energy around us can be stored, converted, and amplified for our use. To help you understand the key energy sources that will play an important role in the world's future, we have designed this page to familiarize you with some of the theory, economics, and problems of the various types of energy. The energy sources have been split into three categories: fossil fuels, nuclear sources and renewable sources.
Fossil fuels have been a widely used source of energy every since the Industrial Revolution just before the dawn of the 20th century. Fossil fuels are relatively easy to use to generate energy because they only require a simple direct combustion. However, a problem with fossil fuels is their environmental impact. Not only does their excavation from the ground significantly alter the environment, but their combustion leads to a great deal of air pollution.

Pollution

Global Warming

You may have probably heard of something called "global warning" before. Perhaps you are also familiar with the term "Greenhouse effect." Because those two terms are so important in understanding the pollution problem associated with burning biomass and fossil fuels, we should touch upon their definitions now. Scientists believe that global warming is caused by the "Greenhouse effect." The greenhouse effect describes the accumulation of carbon dioxide in our earth's atmosphere. A layer of gas forms that traps heat inside the atmosphere, thereby acting as the glass ceiling of a greenhouse. Because heat is trapped by the carbon dioxide, it is believed that the earth is slowly warming. A potential (but relatively distant) danger of global warming is the melting of the so-called "polar ice caps" at the north and south poles. This occurrence would cause the ocean level to rise and perhaps flood many coastal cities.

The Advent of Fossil Fuels

Before humans were around on the earth, there was a relatively even recycling of carbon dioxide and oxygen. Plants require carbon dioxide to live, and they emit oxygen in return. Animals, on the other hand, need oxygen, but exhale carbon dioxide. But as humans began to burn fossil fuels to create energy (especially beginning just before the 20th century during the "Industrial Revolution"), more and more carbon dioxide was emitted into the air until the balance was slowly destroyed.

Renewable Energy

Uncertainty about the future of fusion research has increased the importance of "renewable" energy sources. Among the most important of these sources are hydroelectric, solar, and wind. As you will see, renewable energy sources' main assets are their environmental cleanliness and their virtual inexhaustibility. Major drawbacks, however, are limited energy production (in most cases not suitable for large-scale power generation) as well as relative costliness to build and maintain. In light of diminishing fossil fuels, however, renewable energy may end up as the energy of choice for the 21st century. There are a few types of renewable energy:

Solar energy

The sun

The sun is the sores of all energy. It sends energy in all directions. It is about 150 million km from earth. A large number of energy comes from the sun at the form of light. The temperature of the center of the sun is about 15,000,000 degree Celsius. At this temperature nuclear reactions are taking place the hole time and this are the whole of sun's energy. The sun does not shine one place all the time. There are differences between the amount of energy reaching the earth's surface in different country. In the sunnier parts of the world sunlight is an important source of energy. It can be used for heat water or make electricity. The amount of energy reaching the earth from the sun is thousand times greater than witch we use.
Problems With solar energy

Solar power is actually one of the cleanest methods of energy production known. Because solar panels simply convert the energy of the sun into energy mankind can use, there are no harmful byproducts or threats to the environment. One major concern is the cost of solar power. Solar panels (accumulators) are not cheap; and because they are constructed from fragile materials (semiconductors, glass, etc.), they must constantly be maintained and often replaced. Further, since each photovoltaic panel has only about a 40% efficiency, single solar panels are not sufficient power producers. However, this problem has been offset by the gathering together of many large panels acting in accord to produce energy. Although this setup takes up much more space, it does generate much more power.

hope this helps u out and good luck

there are far more than three types of energy if you are talking about physical sciences. In terms of power, there are also far more than three types. For power there is: solar power, wind power, geothermal energy, and basically anything that can turn a wheel and power a generator. For the other type of energy there is, but not limited to: kinetic energy potential energy, mechanical energy, chemical energy, electric energy, magnetic energy, radiant energy, nuclear energy, heat, mechanical work, lionization, elastic, sound, gravitational, intrinsic, and thermal.
