The World Uses a Variety of Different Energy Sources

The world has a wide range of different energy sources. In 2018 fossil fuels like gas, oil and coal, made up over 81 percent of the energy consumed. Renewable energy sources, such as solar power, wind, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is 5 percent. Different countries use different types of energy sources, in order to balance the environmental aspects with economics.

Nature’s energy is available in a variety of forms such as wind, sun, waves, and ocean. When harnessed and converted into more convenient forms of energy, such as heat or electricity, these are called primary sources. These energy sources become non-renewable sources of energy when they are exhausted.

The environment is harmed by many fossil fuels, along with other non-renewable sources of energy. For instance, oil mining is a destructive process that can destroy the forests of the earth. Hydraulic fracturing (fracking) can trigger earthquakes leonardogiombini.it as well as water pollution. The burning of coal releases carbon dioxide, contributing to global warming.

Fortunately, the majority of the most promising sources of energy are renewable and sustainable. Solar, wind and hydropower could generate, for instance electricity without digging for new sources.

Tidal and Wave Power are two other renewable energy sources that are emerging. However, to be utilized in a large-scale manner they must have efficient distribution networks. These must be built using a source of non-renewable energy sources. These sources aren’t sufficient to provide the majority of our energy requirements. However, it’s important to keep in mind that prices for renewable energy equipment have come down dramatically over the past couple of years, and efficiency is growing quickly.
