The world relies on a variety of different energy sources. In 2018 fossil fuels, like gas, oil and coal, were responsible for more than 81 percent energy consumed. Renewables, like solar power, wind, biomass and hydroelectricity, account for 14 percent. Nuclear energy is 5 percent. Different countries have different energy sources to balance economic needs and environmental concerns.

Nature’s energy is available in a variety of forms like sun, wind waves, and ocean. When harnessed and transformed into more practical forms of energy, like heat or electricity, these are called primary sources. These sources are non-renewable resources of energy when they are exhausted.

A lot of fossil fuels and a few of the other nonrenewable energy sources can be harmful to the environment. Mining oil, for instance can cause the destruction of our planet’s virgin forests. Fracking (hydraulic fracture) could cause water pollution and earthquakes. Burning coal releases carbon dioxide, contributing to global warming.

Fortunately there are many promising sources of energy are renewable and sustainable. Hydropower, solar energy and wind power, for instance, can produce electricity without the need to search for new resources.

Tidal and Wave Power are also sustainable energy sources that are emerging. In order to be utilized at an extensive scale, these technologies require efficient distribution networks. This requires the use non-renewable energy sources https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni/ to build these networks. These sources aren’t able to fulfill the majority of our energy demands. It is important to keep in mind that the cost of renewable energy equipment have dropped dramatically in recent years and efficiency is growing.
