has been some shortage of energies in the world. I think they should build more renewable energies like. Tidal power‚ Similar to a wind turbine‚ many tidal stream generators rotate underwater and is driven by the swiftly moving dense water. Although not yet widely used‚ tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power. Historically‚ tide

energy effectively uses natural resources such as sunlight‚ wind‚ rain‚ tides and geothermal heat‚ which may be naturally replenished. Renewable energy technologies range from solar power‚ wind power‚ hydroelectricity/micro hydro‚ biomass and biofuels for transportation. Solar energy is energy from the Sun in the form of radiated heat and light. Wind power is the conversion of wind energy into useful form‚ such as electricity‚ using wind turbines. Hydroelectricity is a form of hydropower‚ and is

Firstly‚ there are many form of renewable source‚ like the solar system‚ biogas‚ wind turbines‚ nuclear power and hydropower energy. These sources can be recycled and they are gentle to the environment. Secondly‚ it is easy to get these alternative sources.

amounts of power. At the same time our means of production face new problems. International treaties aim to limit the levels of pollution‚ global warming prompts action to reduce the output of carbon dioxide and several countries have decided to decommission old nuclear power plants and not build new ones. Such development brings about the need to replace old energy production methods with new ones. While several are in development‚ including the promising but ever-so-distant nuclear fusion power‚ other

Renewable Energy: Yes or No? Joanna Fain Eng. 122 English Composition II April 15th‚ 2013 Although fossil fuels provide an inexpensive form of energy‚ they have been shown to pollute ecosystems‚ endanger animals and humans‚ are not sustainable‚ and cannot provide nearly the amount of energy that can be obtained from renewable sources. Fossil fuels do provide an inexpensive form of energy‚ but in contrast‚ they also pollute the atmosphere with greenhouse gases‚ thus contributing

green energy. Energy is very important to life. People use energy to keep the house warm‚ the lights on‚ and the food cold. There are many different types of green energy. One type of energy is solar. “Solar panel technologies promising enhanced power output The concept of non-conventional sources of energy is becoming a major subject of research as our planet is running out of its resources of non-renewable energy such as coal‚ petroleum‚ etc” (Athena Information Solutions Pvt.

No other substance can equal the enormous impact which the use of oil has had on so many people‚ so rapidly‚ in so many ways‚ and in so many places around the world” (Duplar 1). There are facts showing that fossil fuels are damaging the environment‚ people’s health

Disadvantages of renewable energy is energy derived from sources that will not run out. Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades‚ and solar collectors

A global energy crisis is defined as any great shortfall in the supply of energy to an economy. Energy is oil‚ electricity‚ or other natural resources like coal and natural gas. When the energy supply to an economy becomes endangered or scarce‚ prices raise to record highs. This paper will cover historical events that caused energy crises in the past‚ recent events that affect today’s energy prices‚ and what is being done and proposed to lessen the United State’s dependence on some forms of non-renewable

A good electricity alternative would be a small hydro power system that uses running water to turn a turbine and produce electricity. This would cut back on the electricity cost and usage.
