Renewable sources of energy Wind energy Wind Energy‚ energy contained in the force of the winds blowing across the earth’s surface. When harnessed‚ wind energy can be converted into mechanical energy for performing work such as pumping water‚ grinding grain‚ and milling lumber. By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator‚ modern wind turbines convert wind energy‚ which turns the rotor‚ into electrical energy. Because wind is a clean and

09-10-09 When you hear the word radioactivity‚ you think directly about dangerous gasses. But radioactivity can also be a way of healing people. The most known are X-rays and radiotherapies. Too much radioactivity is‚ in contrast with radioactive medicines‚ dangerous for your body. You can get seriously sick‚ cancer for example‚ or even die. A tragic example of this is Tsjernobyl‚ where a nuclear reactor exploded. In this essay I will try to answer the question: How can radioactivity help people

behind Energy Drinks 1. When we say that something gives us "energy”‚ what does that mean? What is a biological definition of energy? When we say that something gives us “energy” it means we can get sugars or carbohydrates and lipids from that. Humans need to eat carbohydrates and lipids to provide fuel for our body’s metabolism. Human body must have these chemicals in order to function and different food sources provide different types of energy. The biological definition of energy is the

It is also the world’s biggest net importer of natural resources (Shaffer‚ “The United States” 135). The domestication of energy is the production and consumption of energy from resources found in the home country. Domestic energy can occur from petroleum reserves on public and private lands‚ from using hydraulic fracturing of shale

Geothermal Energy Right now our country and planet as a whole‚ is in an energy crisis. Our non-renewable resources are running out. Oil is at outrageous prices and our economy is suffering. The people of this planet need to start looking for an alternative energy source because our fossil fuels will not last forever. Geothermal energy is one of many different ways we can preserve our fossil fuels. Geothermal energy is better for the environment because it does not involve burning and can not

What is so great about renewable energy? Well‚ because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their‚ unlike coal that once its gone‚ its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun.

Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface‚ and even farther down to the extremely hot molten rock called magma. These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly
