What sources of energy are there




















We use it to drill deep wells and bring very hot underground water to the surface to use this heat. It is used to produce steam and then pumped through a turbine to create electricity.

Tidal and wave energy can also be used as an energy source. This rise and fall of the water can be used to generate electricity. But at some locations, tidal energy may harm wildlife. For example, the tidal barrages, which work much like dams, may harm fish and other species in ocean water. It is a natural source and free. It is available in plenty amount. It is non-polluting.

It does not emit any greenhouse gases. One of the biggest advantages of renewable sources of energy is the ability to avoid the politics and price volatility that is increasingly characterizing fossil fuel markets.

It requires very large initial investments for productive use. It needs a storage system. It requires a large piece of land. These are renewable sources of energy and non-renewable sources of energy. Renewable sources of energy regenerated in a short period of time or are used again and again, but non-renewable sources of energy can not be regenerated in a short time. Crude oil, coal, and natural gas occur in limited and exhaustible quantities, so these are non-renewable sources of energy.

They produce pollution and greenhouse gases. With technological progress, the energy demand is increasing day by day. As our energy demand is increasing, we need to look for more and more sources of energy. We can develop the technology to use the available or known sources of energy more efficiently.

Current wind energy installations power roughly twenty million homes in the United States per year and that number is growing.

Most states in the nation now have some form of wind energy set-up and investment into the technology continues to grow. Unfortunately, this form of energy generation also presents challenges. Wind turbines restrict views and may be dangerous to some forms of wildlife. At its most basic, geothermal power is about extracting energy from the ground around us.

It is growing increasingly popular, with the sector as a whole experiencing five percent growth in The World Bank currently estimates that around forty countries could meet most of their power demands using geothermal power. This power source has massive potential while doing little to disrupt the land. However, the heavy upfront costs of creating geothermal power plants has led to slower adoption than may have been expected for a fuel source with so much promise. Natural gas sources have been in use for a number of decades, but it is through the progression of compression techniques that it is becoming a more viable alternative energy source.

In particular, it is being used in cars to reduce carbon emissions. Demand for this energy source has been increasing. In , the lower 48 states of the United States reached record levels of demand and consumption. Despite this, natural gas does come with some issues. The potential for contamination is larger than with other alternative fuel sources and natural gas still emits greenhouse gases, even if the amount is lower than with fossil fuels.

In contrast to biomass energy sources, biofuels make use of animal and plant life to create energy. In essence they are fuels that can be obtained from some form of organic matter. The energy provided is most often used in power plants, water pumps, and desalination plants.

It is abundant and widely available. Easily predictable. No damage to the land. It is suitable for certain locations. It is highly dependent on the wavelength. They also generate noise and visual pollution. Hydroelectric Energy. It is the energy derived from the movement of water.

It has kinetic energy when it moves, which can be harnessed. Basically, it is the electricity produced by hydropower. It is reliable and adjustable. It is emission-free. It is completely renewable. Higher initial costs. Flood risk. Carbon and methane emissions. Biomass Energy. It is the use of organic material to generate energy. Biomass is just organic matter that is made in nature like dung, grass clippings, etc. It is a renewable source of energy. It is carbon neutral.

It is less expensive than fossil fuels. It's a revenue source for manufacturers.
