The world uses a variety of energy sources. Fossil fuels–including natural gas, petroleum and coal–accounted to more than 81 percent of all energy consumed in the year 2018. Renewable energy sources like wind power, solar energy, biomass, and hydroelectricity https://leonardogiombini.it/ make up 14 percent. Nuclear energy is 5 percent. Different countries employ different sources of energy to meet environmental and economic requirements.
Nature provides energy in a number of forms: sunlight and wind, waves, oceans, and more. When harnessed and transformed into more practical forms of energy, such as heat or electricity, they are called primary sources. When these energy sources are exhausted, they are non-renewable energy sources.
The environment is harmed by many fossil fuels in addition to other non-renewable sources of energy. For instance, oil mining is a destructive process that can destroy the forest ecosystems of the planet. Fracking (hydraulic fracture) can cause earthquakes and water pollution. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately that many of the most promising energy sources are sustainable and renewable. Hydropower, wind and solar, for instance, can produce electricity without the need to search for new sources.
Other renewable energy sources are gaining momentum, such as the wave and tidal power. To be utilized on a large-scale, these technologies require effective distribution networks. This requires the use non-renewable energy sources to build these networks. These sources aren’t sufficient to meet the majority of our energy demands. It is important to be aware that prices for renewable energy-related equipment have fallen drastically over the last few years, and the efficiency is rising rapidly.
