The world relies on a variety of different sources of energy. In 2018 fossil fuels, such as oil, gas and coal, accounted for more than 81 percent energy consumed. Renewable energy sources, such as solar power, wind, hydroelectricity and biomass, account for 14 percent. Nuclear energy is responsible for another 5percent. Different countries employ different combinations of energy sources, in order to balance the environmental aspects with economics.

Nature’s energy comes in many forms including sun, wind waves, and ocean. When harnessed and transformed into more efficient forms of energy, such as heat or electricity, they are known as primary sources. These sources are non-renewable resources of energy when they are exhausted.

The environment is damaged due to a wide range of fossil fuels as well as some other sources of energy that are not renewable. For example, mining for oil can destroy the forests of the planet. Fracking (hydraulic fracturing) could cause water pollution and earthquakes. Carbon dioxide is released when coal is burned which causes global warming.

Fortunately that many of the most promising energy sources are renewable and sustainable. Hydropower, solar energy and wind power for instance, are able to produce electricity without having to search for new sources.

Tidal and Wave Power are two other sustainable energy sources that are gaining popularity. In order to be utilized at an extensive scale, these technologies require efficient distribution networks. They need to be constructed using a source of non-renewable energy. These sources aren’t able to satisfy the majority of our energy needs. However, it’s important to be aware that prices for renewable energy equipment have decreased drastically over the last few years, and efficiency is growing quickly.
