The world is awash with a variety of energy sources. Fossil-based fuels such as natural gas, oil, and coal–accounted for over 81 percent of all energy consumed in the year 2018. Renewable energy sources such as solar energy, wind power biomass, hydroelectricity, and biomass comprise 14 percent. Nuclear energy is another 5 percent. Different countries have different types of energy sources, in order to balance economic needs with environmental concerns.
Nature provides energy in many forms including sun, wind waves and ocean. These sources of energy are transformed into more convenient forms of energy, like electricity or heat, when they are harnessed. These sources of energy become non-renewable sources of energy when they are exhausted.
A lot of fossil fuels and a few of the other sources of energy that aren’t renewable are causing harm to the environment. For instance, mining for oil can take away the planet’s forests. Fracking (hydraulic fracturing) can lead to water pollution and earthquakes. Carbon dioxide is released when coal is burned which causes global warming.
Fortunately that many of the https://leonardogiombini.it/2021/07/05/generated-post/ most promising sources of energy are sustainable and renewable. Wind, solar and hydropower can create, for instance, electricity without having to dig up new sources.
Other sources of sustainable energy are emerging, including the wave and tidal power. In order to be utilized at an enormous scale, these technologies need to have effective distribution networks. This requires the use of non-renewable energy sources to construct these networks. In the end, these sources are not yet enough to supply the majority of our energy requirements. It’s vital to remember that the prices of renewable energy equipment have decreased dramatically in recent times and the efficiency is rising.
