The World Uses a Variety of Different Energy Sources

The world is dependent on a range of different sources of energy. Fossil-based fuels such as natural gas, petroleum and coal accounted for more than 81 % of the energy consumed in 2018. Renewable energy sources, such as solar power, wind, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is responsible for another 5%. Different countries have different energy sources to balance the environmental and economic demands.

Nature’s energy comes in many forms: sun, wind, waves and ocean. When harnessed and converted into more efficient forms of energy, such as electricity or heat, these are https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure called primary sources. When those energies are exhausted, they are nonrenewable energy sources.

The environment is harmed by many fossil fuels, along with other energy sources that aren’t renewable. For instance, mining for oil can take away the planet’s forests. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. The combustion of coal releases carbon dioxide, which contributes to global warming.

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

Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. However, to be utilized on a massive scale, these technologies must have effective distribution networks. They must be constructed which will require the use of non-renewable energy. These sources aren’t sufficient to satisfy the majority of our energy needs. It’s still important to remember that the cost of renewable energy equipment has drastically decreased in recent years and the efficiency of these equipments is growing.
