The world is dependent on a range of official website different sources of energy. In 2018, fossil fuels, such as oil, gas and coal, comprised more than 81 percent of energy consumed. Renewables, including solar power, wind, hydroelectricity and biomass, account for 14 percent. Nuclear energy is another 5 percent. Different countries have different energy sources to balance economic needs and environmental concerns.

Nature’s energy comes in many forms like sun, wind waves and ocean. These sources of energy can be transformed into more practical forms of energy, like electricity or heat when they are harnessed. These energies 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 strip the planet’s pristine forests. Fracking (hydraulic fracturing) could cause water pollution and earthquakes. The combustion of coal releases carbon dioxide, which contributes to global warming.

Fortunately, a majority of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower could generate, for instance electricity without the need to dig up new sources.

Tidal and Wave Power are also renewable energy sources that are gaining popularity. To be utilized on an extensive scale, these technologies need to have effective distribution networks. These need to be built using a source of non-renewable energy. Therefore, these sources aren’t enough to supply the majority of our energy requirements. It is important to be aware that prices for renewable energy equipment have decreased drastically over the last couple of years, and efficiency is growing quickly.
