1. Solar: Solar power is one of the cleanest sources of energy, because solar panels simply convert the energy of the sun into energy that humans can use without any harmful byproducts or threats to the environment. One of the concerns is the cost. Solar panels which are referred to as accumulators are fairly expensive. They are constructed from fragile materials (semiconductors, glass, etc.) and must constantly be maintained and frequently replaced.
2. Wind: Wind generators are being used, particularly in large offshore wind farms. Wind rotates turbine blades, which turns prop shafts connected to an electrical generator, creating electricity. There is much controversy in regards to wind power. On land, wind turbines suffer from the unpredictability of weather and blade rotation also causes a change in weather patterns on the ground area. Birds, such as eagles and other flying animals have been hurt and killed by wind turbines, and there is also human health concerns called “Wind Turbine Syndrome”. Other concerns are deforestation, excavation, and erosion.
On the other hand, wind power promises a clean and free source of electricity that would reduce our dependence on imported fossil fuels and the output of greenhouse gases and other pollution. Many governments are therefore promoting the construction of vast wind “farms,” encouraging private companies with generous subsidies and regulatory support, requiring utilities to buy from them, and setting up markets for the trade of “green credits” in addition to actual energy. Energy companies are eagerly investing in wind power, finding the arrangement quite profitable.
3. Hydroelectric: Hydroelectric power involves building a dam and using the energy of the enclosed water to power turbines connected to an electrical generator. It has an inexhaustible fuel source, useful levels of energy production, and can be used around the world.
This form of power is one of the cleanest and most environmentally friendly sources of energy, but it also has the capability of damaging effects on surrounding areas, not to mention the change in water quality. Because of how hydroelectric systems work, the water often has a higher temperature, loses oxygen content, experiences siltation and gains in phosphorous and nitrogen. It also is extremely expensive to construct and entirely dependent on rainfall to top-up the water level.
They have also been known to adversely effect aquatic life, especially salmon. Fortunately, this problem has been dealt with by the production of “fish ladders”. These structures provide a pathway for fish to navigate past the hydroelectric dam construction.
4. Biodiesel: Biodiesel are fuels that are mainly derived from products that would well be disposed of, such as grease, vegetable oils, and animal wastes. Most biodiesel uses oil from crops, most commonly ethanol from corn, to power cars. Biofuels can be produced from any number of plant crops; most ethanol in the world today is being derived from corn, with sugar cane increasingly gaining favor. Sugar cane provides double the yield per acre as opposed to corn. Biofuels favored by the Americas–Brazil and the U.S. produce 90 percent of the world’s ethanol between them.
Most existing cars can use them immediately, at least in small doses. Most gasoline-fueled cars can take up to a 10 percent ethanol blend in their fuel without any conversions. They are generally better for your health when burnt too, reducing tailpipe carbon monoxide emissions by up to 30%, and fine particulate matter emissions by 50%, according to the Renewable Fuels Association.
There are other alternative energy solutions and research is continually progressing. There are many alternatives to oil and gas, but so far no one has come up with the perfect solution because there are many factors to weigh. We need to find the right solution that will be cost-effective but will not cause harm to humans, animals, or our environment.
