The world is dependent on a range of energy sources. In 2018 fossil fuels like gas, oil and coal, were responsible for over 81 percent of the energy consumed. Renewable sources such as wind power, solar energy biomass, hydroelectricity and biomass account for 14 percent. Nuclear energy accounts for another 5 percent. Different countries have different combinations of energy sources, and are able to balance economic needs with environmental concerns.
Nature provides energy in a number of forms, including sunlight winds, waves oceans, and more. These primary sources are transformed into more convenient energy forms, such as electricity or heat when they are harnessed. When the energy source is exhausted, they turn into nonrenewable energy sources.
The environment is harmed due to a wide range of fossil fuels and also other energy sources that aren’t renewable. Oil mining, for instance can cause the destruction of our planet’s virgin forests. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. The combustion of coal releases carbon dioxide, which contributes to global warming.
Fortunately, some of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower produce, for instance, electricity without the need to dig up new sources.
Tidal and Wave you could try this out Power are two more sustainable energy sources that are gaining popularity. However, to be utilized at a large scale they must have efficient distribution networks. They must be constructed which will require the use of non-renewable energy. This means that these sources are not yet enough to supply the majority of our energy needs. It is important to keep in mind that prices for renewable energy-related equipment have fallen significantly in the past couple of years, and efficiency is growing quickly.
