We can use less the fossil fuels by leveraging alternative energy sources more effectively. The dirty coal energy plants can be decommissioned by turning to alternatives to these energy sources. There is a lot of energy that can be produced naturally if society only tries to research and develop the technologies needed to do so. One of these renewable energy resources is solar energy. Solar PV cells continue to be developed that are often more energy efficient and less costly than cells from a few years ago. Solar energy farms have been growing in many nations, and they have started to be more strategically placed. Into the future, they are not jeopardizing birds as previous placement of solar panels may have caused. The following sections provide a summary overview of many other renewable energy sources being researched, developed, and deployed throughout the world. Ocean current energy is seen by governments and corporations as having enormous energy generating possibilities. A wave electricity generator in Europe has been in operation for a long time. It is thought to be a great accomplishment. The progressive countries across the globe are also running experimental facilities. Hydroelectric power has been with us for a while. Where it is set up, it is a clean generator of electricity. Because water and gravity is used, it is cleaner than a grid powered by natural gas. There are restrictions to the availability of the correct places to set up a large dam. Many river based, or small and localized, hydroelectric generators have been set up in recent times due to this limitation. Geothermal energy is extremely abundant. Since it lies directly beneath us, we only need look just a few miles below the earth's surface to find huge amounts of energy. This energy is produced by the heating of water, located within the Earth, through the actions of earth's fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Increased efforts should be put into geothermal energy production. Biodiesel energy is created out of the oils contained in crops. Most commonly, the retail stockpiles of biodiesel have been created using rapeseed and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with renewable energy. Venture interest from companies across the World is increasing. Biodesiel burns much better than fossil fuel diesel. Another renewable energy resource is solar energy. It is the one that is most well known every day. Solar technology involves the manufacturing of solar systems which gather and focus the power given off directly by the sun, and convert it into electricity. In other cases, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.
