What are the 5 main sources of renewable energy?

What is the impact on the planet of generating energy from non-renewable sources?

However, there is concern that these are types of energy based on finite resources, which will eventually run out, making it necessary to look for alternatives to cover society’s future energy demand.    On the other hand, the use of non-renewable energies also generates waste and emissions of polluting gases into the atmosphere, which, on a large scale, represent a great risk to people’s health.

Other energy transitions have already taken place in the past, but the energy transition in the 21st century is very much determined by the phenomenon known as “global warming” (the inability of the earth system to absorb the greenhouse gas emissions that are currently occurring).

Non-renewable energy sources examples

Renewable energies are clean, inexhaustible and increasingly competitive sources of energy. They differ from fossil fuels mainly in their diversity, abundance and potential for use anywhere on the planet, but above all in that they do not produce greenhouse gases – the cause of climate change – or polluting emissions. Moreover, their costs are falling steadily, whereas the general trend in the cost of fossil fuels is the opposite, regardless of their cyclical volatility.

According to the IEA, global electricity demand will increase by 70% by 2040, raising its share of final energy use from 18% to 24% over the same period, driven mainly by emerging regions (India, China, Africa, the Middle East and Southeast Asia).  DISCOVER WHAT RENEWABLE ENERGIES ARE IN 2 MINUTESRenewable energies are those that are obtained from inexhaustible natural sources and generate electricity without contributing to global warming.

Energy sources

Renewable energy is the energy obtained from virtually inexhaustible natural sources, either because of the immense amount of energy they contain, or because they are capable of regenerating themselves by natural means.[1] Renewable energy is the energy obtained from wind turbines that harness the kinetic energy of the wind, transforming it into electrical power.

The energy is obtained by means of wind turbines that harness the kinetic energy of the wind by transforming it into electrical energy. This resource can be described as perpetual, and the amount potentially obtainable in a given geographical area depends on the wind regime and the orography of the site.

A similar, but not identical, concept is that of renewable energies: an alternative energy, or more precisely an alternative energy source, is one that can replace conventional energies or energy sources,[2] either because of its less polluting effect, or fundamentally because of its possibility of renewal.

Energy consumption is one of the great gauges of a society’s progress and welfare. The concept of energy crisis appears when the energy sources from which society is supplied are exhausted or become drastically more expensive. An economic model such as the current one, whose functioning depends on continuous growth, also requires an equally growing demand for energy. Since fossil and nuclear energy sources are finite, it is inevitable that at a certain point the demand cannot be met and the whole system will collapse, unless other new methods of obtaining energy are discovered and developed: these would be alternative energies.
