The world has a myriad of energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent of energy consumed. Renewables such as solar power, wind power biomass, hydroelectricity, and biomass make up 14 percent. Nuclear energy is responsible for another five percent. Different countries have different types of energy sources, and are able to balance the needs of the economy with environmental concerns.
Energy is present in nature in many forms: sunlight winds, waves ocean and more. These sources of energy can be transformed into more practical forms of energy, like electricity or heat when they https://leonardogiombini.it/2021/07/13/generated-post-2/ are harnessed. These energy sources become non-renewable sources of energy when they are exhausted.
Many fossil fuels as well as some of the other sources of energy that aren’t renewable can be harmful to the environment. For instance, oil mining is a destructive process that can destroy the planet’s virgin forests. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. Carbon dioxide is released when coal is burned which causes global warming.
Fortunately, a lot of the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower could create, for instance, electricity without the need to dig for new sources.
Other renewable energy sources are emerging, such as tidal and wave power. To be used on large scale, these sources of energy require efficient distribution networks. This requires the use non-renewable energies to build these networks. These sources aren’t able to fulfill the majority of our energy requirements. It is important to keep in mind that the cost of renewable energy equipment has decreased dramatically in recent times and the efficiency of these equipments is growing.
