The world relies on a variety of different energy sources. Fossil-based fuels such as oil, natural gas and coal–accounted to more than 81 percent of all energy consumed in the year 2018. Renewable energy sources like solar energy, wind power, biomass, and hydroelectricity comprise 14 percent. Nuclear energy is 5 percent. Different countries employ different mixes of energy sources, while balancing environmental and economic requirements.
Nature’s energy is available in a variety of 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 sources are non-renewable resources of energy when they are exhausted.
The environment is harmed due to a wide range of fossil fuels along with other sources of energy that are not renewable. For instance mining for oil may strip the planet’s pristine forests. Hydraulic fracturing (fracking) can cause earthquakes and pollute the water. Carbon dioxide is released when coal is burnt and contributes to global warming.
Fortunately there are many promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, are able to produce electricity without the need to dig for new supplies.
Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. To be utilized on https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ an enormous scale, these technologies need to have effective distribution networks. They need to be constructed which will require the use of non-renewable energy sources. Therefore, these sources aren’t enough to supply the majority of our energy requirements. It is important to keep in mind that the cost of renewable energy equipment have dropped dramatically in recent years and the efficiency is rising.
