It is hard to live without Energy, but it is impossible to find another planet to live in. Energy is everything. It comes in many forms such as heat, electricity, light, mechanical energy. Conventional energy sources such as coal and oil are the main contributors to the global warming. Further more, these fossil fuels are not renewable, which means one day we will run out of them. The good news is alternative sources of energy can replace the current technologies we are using. These renewable energy sources are environment friendly as they emit less carbon dioxide, compared to fossil fuels. There are many alternative sources of energies that harness natural forces and resources such as solar power, wind power, and geothermal energy.
From environmental prospective solar power is the best alternative source of energy. It is the light and the heat from the sun which is harnessed to generate power. It is created by converting the sun rays into electricity using solar panels. Additionally, solar panels change the sun light that hit it into heat, which is used to heat homes, water, swimming pools, and for cooking. There is also another energy sources that is safe and natural in the same time.
Wind power is one of the oldest forms of energy that benefited mankind so greatly. It is the use of the wind power to produce electricity. In the past, people used it to navigate water, to pump water and to dry clothes. Today, we use it to produce electricity. In this technology, when the wind blows, it rotates the blades of the wind turbines. This rotation runs electric generators. There is one more source of energy which can be used as an alternative to fossil fuels.
Geothermal energy is one of the main sources of alternative energy. It is the heat of the earth, which is continuously produced in the core of the earth. It is very beneficial to the earth and it atmosphere as it doesn't produce any pollution. In this technology, Wells are drilled to pump heated water and steam. Then, that steam and heated water are purified to drive wind turbines which produce electricity. It works best in sunny climate regions.
Energy is everything. It can be found in many forms. Fossil fuels cause many environmental issues due to the emission of carbon dioxide. However, alternative source of energy can substitute traditional energy sources with almost no negative effects on the environment. One of the alternative energy sources is solar power. In smaller scale, it is used to heat houses, water and in cooking. In larger scale, it is used to generate electricity. Another source is wind power. Older wind turbines used to grind crops, now to run generators and generate electricity. A third source is geothermal energy, in which, heated water and steam are used to run generators.
resources. Governments and concerned individuals are working to make the use of
renewable sources resources a priority, and to lessen the irresponsible use of natural supplies
through increased conservation. The non-renewable sources are getting depleted very fast, because of its heavy usage throughout the world. The natural resources are being used in making electricity majorly, then in gas, kerosene, etc. Technology is now one of most used thing in the world, using large quantity of electricity. 41% of the world’s electricity is used by coal, thus the over use of electricity, is consuming coal and other fossil fuels, like oil, natural gas, etc. The most common non-renewable sources are natural gas, crude oil, nuclear power,
coal, etc. They are all quickly reducing, in the crust of the world. The useage is growing more and more, and so its is reducing. There are many renewable sources which do have many advantages like: Water- Provides 19% of alacrity, expands irrrigation, provdes drinking water, supplies hydroelectirc energy, it is cheaper. Wind power- Clear source of energy, no emission into the atmoshpere, does not add to thermal burden of the earth, etc. Though it does have disadvantages like: Water, it destabilizes marine ecosystems, dam building is very costly, people have to relocate, pollution affects water power, etc. For wind there are disadvantages like: most places wind power density is low, land consumption, etc.
Non- renewable sources for example are fossil fuels, they are organic remains which have through the process
of fossilisation over millions of years, became coal, oil and natural gas. They can not be renewed over time, as they take million of years for fossilisation to happen. Nuclear fuels are also non-renewable sources of energy. The earth contains huge stocks of these sources, but they are ﬁxed in quantities and are being steadily depleted/ Renewable sources of energy, rely on natural energy ﬂows and sources in the environment and thus have the
potential of being continually replenished. Examples of renewable sources are solar, wind, water, etc. They are different sources which are not going diminish. Natural gas has its advantages and disadvantages. Its advantages are- its pollutes less, 70% less carbon dioxide
compared to other fossil fuels, does not produce asked after energy release, inexpensive compared to coal, no odor until added. The drawbacks are its not a renewable sources, ﬁnite resources trapped in the earth, etc. Crude Oil
