The world is awash with a variety of energy sources. Fossil-based fuels such as natural gas, oil and coal–accounted for more than 81 % of all energy consumed in 2018. Renewable energy sources like wind power, solar energy biomass, hydroelectricity and biomass account for 14 percent. Nuclear energy accounts for another five percent. Different countries employ different energy sources to balance the environmental and economic demands.

Nature’s energy comes in many forms such as wind, sun, waves and ocean. These primary sources can be transformed into more practical energy forms, such as electricity or heat, once they are find out this here harnessed. These energy sources become non-renewable sources of energy once they have been exhausted.

A lot of fossil fuels and a few of other energy sources that are not renewable are causing harm to the environment. For instance, mining for oil can take away the planet’s forests. Fracking (hydraulic fracture) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burned which contributes to global warming.

Fortunately, many of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower can, for example, generate electricity without having to dig up new sources.

Tidal and Wave Power are two other renewable energy sources that are gaining popularity. However, in order to be utilized in a large-scale manner they must have efficient distribution networks. They need to be constructed which will require the use of non-renewable energy sources. This means that these sources aren’t able to provide the bulk of our energy requirements. Still, it’s important to keep in mind that prices for renewable energy-related equipment have fallen drastically over the last couple of years, and efficiency is increasing rapidly.
