The world uses a variety of different sources of energy. In 2018 fossil fuels, such as oil, gas and coal, accounted for over 81 percent of the energy consumed. Renewables such as solar power, wind power biomass, hydroelectricity, and wind power account for 14 percent. Nuclear energy is another 5 percent. Different countries have different energy sources to balance the needs of their economy and environmental concerns.

Nature is a rich source of energy in many forms, including sunlight as well as wind, waves oceans and more. These sources of energy transform into more efficient energy forms, such as electricity or heat, when they are harnessed. When the energy source is used up, they become nonrenewable energy sources.

The environment is damaged due to a wide range of fossil fuels in addition to other non-renewable sources of energy. For instance, mining for oil can take away the planet’s forests. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. The combustion of coal releases carbon dioxide, which contributes to global warming.

Fortunately there are many promising energy sources are sustainable and renewable. Hydropower, solar energy and wind power for instance, could produce electricity without having to search for new resources.

Tidal and Wave Power are also renewable energy sources that are emerging. To be utilized on large scale, these sources of energy need to have effective distribution networks. This requires the use non-renewable energy sources to build these networks. These sources are not able to meet the majority of our energy needs. However, it’s important to keep in mind that the costs for renewable energy technical managerial areas in the civil infrastructure equipment have dropped drastically over the last few years, and their efficiency is growing rapidly.
