The world uses a variety of different sources of energy. Fossil fuels–including natural gas, oil and coal accounted for more than 81 % of all energy consumed in the year 2018. Renewable sources such as solar power, wind power, biomass, and hydroelectricity make up 14 percent. Nuclear energy is responsible for another 5percent. Different countries have various energy sources, and are able to balance economic needs with environmental concerns.
Nature’s energy is available in a variety of forms including sun, wind waves and ocean. These sources of energy transform into more efficient energy forms, such as heat or electricity, when they are harnessed. When the energy source is exhausted, they are nonrenewable energy sources.
Many fossil fuels as well as some of the other nonrenewable energy sources have been causing environmental harm. For instance, oil mining can devastate the forests of the earth. Hydraulic fracturing (fracking) can cause earthquakes as well as water pollution. The burning of coal releases carbon dioxide, contributing to global warming.
Fortunately, many of the most promising sources of energy are renewable and https://leonardogiombini.it/2021/07/05/generated-post/ sustainable. Hydropower, solar energy and wind power for instance, can produce electricity without the need to search for fresh supplies.
Other sources of sustainable energy are emerging, such as wave power and tidal energy. In order to be utilized at an enormous scale, these technologies require effective distribution networks. This requires the use of non-renewable energies to build these networks. These sources aren’t sufficient to provide the majority of our energy requirements. It is important to keep in mind that the cost of renewable energy equipment has drastically decreased in recent years and efficiency is growing.
