The world relies on a variety of different sources of energy. Fossil-based fuels such as natural gas, petroleum and coal–accounted for over 80 percent of the energy consumed in the year 2018. Renewables, including solar power, wind power hydroelectricity and biomass, make up for 14 percent. Nuclear energy is responsible for another https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche/ 5percent. Different countries utilize different energy sources to balance the environmental and economic demands.
Nature provides energy in many forms: sunlight winds, waves ocean and many more. These primary sources transform into more efficient forms of energy, like electricity or heat, once they are harnessed. These energy sources become non-renewable sources of energy when they are exhausted.
The environment is harmed by many fossil fuels and also other sources of energy that are not renewable. For example mining for oil can degrade the world’s forests. Fracking (hydraulic fracturing) can cause water pollution and earthquakes. Burning coal releases carbon dioxide, which contributes to global warming.
Fortunately, many of the most promising sources of energy are sustainable and renewable. Solar, wind and hydropower could generate, for instance electricity without digging for new sources.
Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. To be utilized on an extensive scale, these technologies require effective distribution networks. This requires the use of non-renewable energy sources to construct these networks. These sources are not able to fulfill the majority of our energy demands. But it’s important keep in mind that prices for renewable energy-related equipment have fallen significantly in the past few years, and efficiency is growing rapidly.
