The world relies on a variety of energy sources. In 2018 fossil fuels like gas, oil and coal, comprised more than 81 percent of energy consumed. Renewable energy sources such as solar power, wind power biomass, hydroelectricity, and biomass account for 14 percent. Nuclear energy accounts for another five percent. Different countries utilize different energy sources to balance the environmental and economic demands.
Nature provides energy in many forms including sun, wind waves, and ocean. These sources of energy are transformed into more convenient forms of energy, like electricity or heat when they are harnessed. When those energies are exhausted, they are non-renewable energy sources.
Many fossil fuels, as well as some of the other sources of energy that aren’t renewable are causing harm to the environment. For instance, oil mining can cause the destruction of our forests of the earth. Hydraulic fracturing (fracking) can trigger earthquakes as well as water pollution. The burning of coal releases carbon dioxide, contributing to global warming.
Fortunately that many of the most promising energy sources are renewable and sustainable. Solar, wind and hydropower could, for example, generate electricity without the need to dig for new sources.
Tidal and Wave Power are also sustainable energy sources that are emerging. However, in order to be utilized on a massive scale these technologies require effective distribution networks. They must be constructed using a source of non-renewable energy. As a result, these sources https://leonardogiombini.it/2021/07/13/generated-post-2/ are not yet capable of meeting the majority of our energy needs. But it’s important keep in mind that prices for renewable energy equipment have come down significantly in the past couple of years, and efficiency is growing rapidly.
