The world has a myriad of energy sources. In 2018 fossil fuels such as oil, gas and coal, comprised over 81 percent of the energy consumed. Renewables, like solar power, wind power, hydroelectricity and biomass, account for 14 percent. Nuclear energy accounts for another 5 percent. Different countries utilize different energy sources to balance the environmental and economic demands.
Nature’s energy comes in many forms such as wind, sun, waves and ocean. These primary sources transform into more efficient energy forms, such as electricity or heat, once they are harnessed. When these energy sources are exhausted, they are non-renewable energy sources.
Many fossil fuels and some of the other sources of energy that aren’t renewable are damaging the environment. Oil mining, for instance can devastate the forest ecosystems of the planet. Hydraulic fracturing (fracking) can trigger earthquakes and pollute the water. The burning of coal releases carbon dioxide, which contributes to global warming.
Fortunately, a lot of the most promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, are able to generate electricity without having to search for fresh my latest blog post supplies.
Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. But, in order to be used on a massive scale these technologies need efficient distribution networks. These need to be built using a source of non-renewable energy sources. These sources aren’t enough to meet the majority of our energy needs. However, it’s important to keep in mind that costs for renewable energy-related equipment have fallen drastically over the last couple of years, and efficiency is rising rapidly.
