Non-renewable energy sources are not effective, and cost far more than they offer in benefits. Fossil fuels formation is a very long process that occurs over thousands of years, and the reserves left in the earth are running out. Developing countries, including China and India, are requiring more energy and oil, and this means what fossil fuel reserves are left will soon be gone. Because of the time fossil fuel formation takes in the earth, it can not be renewed for thousands of years

Wind may be used as an alternative source of energy. If your house is located on at least an acre of flat land, you could efficiently generate power. The major limitations with wind are that there may be mechanical breakdowns on the turbine unit requiring repair. Additionally birds or insects my be killed by colliding with the turbine blades.

Fossil fuels are slowly being used up, and alternative energy sources that are renewable will have to be found to avert an energy crisis and supply the energy needed. Crude oil is full of hydrocarbons, and both the crude and refined forms of this substance contribute greatly to pollution and global warming increases. This energy source is not renewable, which means gasoline and diesel will not be fuel sources much longer. Because fossil fuels are not renewable, they can not be replaced. Removing these resources damages the earth, and new oil fields are getting harder to find every year. Anyone who understands how petroleum engineers find new oil fields knows the extended amount of time and large amounts of money this process requires

Renewable energy sources are all around us. We see them and sense them every time we go outside or even look out a window. There is no shortage of ideas for outstanding renewable energy science fair projects. Explore these suggestions and take your pick!There are many sources of energy that are renewable and considered to be environmentally friendly and harness natural processes. These sources of energy provide an alternate cleaner source of energy, helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resource to create the energy. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work ” for example for electricity generation, water desalination, or the pumping of water (into reservoirs). Wave energy can be difficult to harness due to the unpredictability of the ocean and wave direction. Wave farms have been created and are in use in Europe, using floating Pelamis Wave Energy converters.

The first of the top three renewable energy sources is solar energy, and is probably the best known method. The sun is our most powerful, natural energy source. Solar energy which is sunlight, can be implemented for light, heat, cooling homes, electricity, heating water, and much more industrial processes. Most renewable energy forms are derived either indirectly or directly from the sun. For instance, the heat from sun makes the wind blow. This in turn contributes to growth of plants and trees used for biomass energy. This plays an important role in the evaporation and precipitation cycle that empowers hydropower.

Photovoltaic (PV) Solar power is harnessing the suns energy to produce electricity. One of the fastest growing energy sources, new technologies are developing at a rapid pace. Solar cells are becoming more efficient, transportable and even flexible, allowing for easy installation. PV has mainly been used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.

Alternative energy sources such as wind and water are perfect energy sources. They are simple, cheaper, non-polluting as well as efficient. Alternative energy sources emit no carbon dioxide, which is a great help in reducing global greenhouse emission. These other means of obtaining energy lessens our dependency on limited reserves of fossil fuels. Renewable energy sources capture the mechanical power of wind or water and convert it to electricity. There are enough sources of renewable energy to provide present world’s energy needs. The only challenge is to formulate the capacity to efficaciously and economically get, save and use the energy when needed.
