Why we need another source of Energy ?

The need for alternative sources of energy becomes urgent, therefore, the development of Renewable energy is fast moving. The national and international individuals and companies in the research is creating new and exciting energy system. Some of these are major operations and the need for improving muscular use. Politician in the world are developing policies and agreements are in higher use of energy sources.

The first problem is that the depletion of Fossil fuels in a rapid pace and are more difficult to recover. The result is that we may be facing an energy crisis in the future is that we are not careful now. Energy prices sky rocket and not available for many individuals or countries. To avoid this situation, we must find alternatives and use their full potential. Luckily, it was happening.

The second problem is that Fossil fuels, which are widely used today are harmful to the environment. In early seventies and eighties, there are people and even scientists who preach the opposite, but today the negative effects are shown. The earth is warming and climate change. Some parties in the world, there is more rain and Sundays and other parts are coming hair after they are. Another negative effect is that the ozone layer is thinner, which also leads to a warming world. These two effects complement each other and make it more important to a further step in a different direction. This step will lead us to the use of Renewable energy.

Another problem lies in the development of small economies. Because energy prices for crude oil is through the roof, these more countries suffer. Many countries require crude oil for electricity and transportation. The high oil prices and their impact on almost everything. The monthly cost of electricity for households has increased in others, such as transportation costs and prices. Thus, the high oil prices make it more difficult for small countries to develop economies ago.

The solutions to these problems can be solved by renewables. Our beautiful planet gives us the opportunity to make us one of sunlight, water, strong winds, and hot springs and open it to energy. The sources of energy is abundant and free to use. We should we convert the energy in the right way, without causing other problems that can harm our environment again. Fortunately, many efforts by individuals and companies show that it can be done.

Description of Energy

Appear in different forms - heat (thermal), light (heat), mechanical, electrical, chemical, and nuclear energy. Energy in all things. We use energy to do all that we do, from making direct shot to baking our favorite cookies to sending astronauts to the space - energy is there, so we have the power to do it all. There are two types of energy - stored (potential) and labor (kinetic) energy. For example, eating food that contains chemical energy, and your body stores this energy until you release when you work or play. Learn more about the various forms of energy.

What the kind of Energy ?

All forms of energy that is stored in various ways, the energy source that we use every day. These sources are divided into two groups :

• Renewable Energy (an energy source that can be replenished in a short time).
• Nonrenewable Energy (an energy source that we used up and can not return in a short time).

Both of them can be used to produce secondary energy sources including electricity and hydrogen.

Sources of energy including solar energy that comes from the sun and can be changed into heat and electricity. Wind, geothermal energy from the earth, biomass from plants, and hydropower and energy from the sea water is also a source of energy.

However, we get most of our energy from nonrenewable energy sources, including the fossil fuels - oil, natural gas, and coal. They're called fossil fuels because it was formed during the millions and millions of years by the action of heat the Earth's core and pressure from rock and soil in permanent (or "parents") of plants and animals die. Nonrenewable energy sources are uranium elements, we split the atom (via a process called nuclear fission) to create heat and ultimately electricity.

What are the energy used for ?

• We use all energy sources to generate electricity that we need for our homes, businesses, schools, and factories. Electricity "energizes" our computers, lights, refrigerator, washing machine, and AC, to name only a few uses.
• We also use our energy to run cars and trucks. Both the gasoline used in cars, and solar used in the truck that is made from oil. Propane fuel that is outside our grills and hot air balloon is made of light oil and natural gas.
