The World Uses a Variety of Different Energy Sources

The world relies on a variety of different sources of energy. Fossil fuels, including natural gas, oil, and coal accounted for more than 81 percent of all energy consumed in 2018. Renewable energy sources like wind power, solar energy biomass, hydroelectricity and biomass are responsible for 14 percent. Nuclear energy accounts for another 5%. Different countries have different sources of energy to meet the environmental and economic demands.

Energy is present in nature in a number of forms: sunlight winds, waves oceans, and more. These sources of energy can be transformed into more practical forms of energy, like electricity or heat when they are harnessed. When those energies are exhausted, they turn into non-renewable energy sources.

A lot of fossil fuels and a few of the other sources of energy that aren’t renewable are causing harm to the environment. Oil mining, for instance can devastate the forest ecosystems of the planet. Hydraulic fracture (fracking) can cause earthquakes and pollute the water. Burning coal releases carbon dioxide, contributing to global warming.

Fortunately there are many promising energy sources are renewable and sustainable. Solar, wind and hydropower can create, for instance, electricity without digging up new sources.

Other renewable energy sources are emerging, including the wave and tidal power. To be utilized on a large-scale, these technologies my latest blog post require effective distribution networks. These need to be built using a source of non-renewable energy sources. These sources are not able to meet the majority of our energy needs. It is important to keep in mind that the cost of renewable energy equipment have dropped dramatically in recent years and the efficiency is rising.
