The Scope of Renewable Energy

We got used to thoughtless use of resources such as oil, gas, coal, and this caused the current situation – mankind is on the threshold of the energy crisis. The stock of these fuels is constantly decreasing. Renewable energy is the best future for people and our planet without any exaggeration.

Renewable Energy and Its Varieties

The place of fossil fuels in modern energy sector proves one fact – most countries of the world greatly depend on oil, gas, and coal. And this point conceals many risks and dangers. Despite the fact that fossil fuels have a natural origin, as they were formed in the result of complex chemical and physical processes in nature, retrieving of coal, peat and other fuels causes significant destruction of the environment and requires a lot of expenses. For that reason, people are looking for some alternatives that can both meet the need of modern people and at the same time are environmentally friendly.

In this case, it’s high time to ask essay writers to take a look at renewable energy and benefits it provides. First of all, you should clearly understand one thing – renewable energy is a tool that can be used not only by contemporaries but also future generations. It will never run out, so our descendants will be energy secured. Experience of many countries has shown dependence on foreign resources may have a negative impact on the economy as a whole. Investing in renewable energy we develop largely a regional economy and offer job opportunities to locals. But more importantly, this type of energy doesn’t deplete nature and pollute the environment.

Keep Your Face to the Sun

It is no secret that the Sun is the source of life on our planet, and it’s almost impossible to imagine a human being without it. Sunlight is a real treasure for us because it can be used in many ways for commercial and domestic purposes, e.g. to light and heat buildings, to heat water, to cool some stuff, and to produce electricity.

Solar energy can be considered as a universal resource, as it also affects other natural phenomena, for example, the winds. By means of wind turbines, people have learned to capture wind energy and transform it. But it’s not over yet, solar heat and the winds to a large extent determine the circulation of water in nature. Under their influence water evaporates and then water vapor turns into rain or snow that fall into rivers and lakes. At this stage, water energy is captured by hydroelectric power stations.  

Sunlight and water are necessary conditions for the growth of plants which consist of organic matter known as biomass. The use of biomass for the production of fuel, chemicals, and electricity is an extremely promising area which is called bioenergy.

Believe in the Power of Water

More than 70 % of the Earth’s surface is covered with water, and oceans occupy a large part of this amount. The World Ocean has a huge potential for generation of energy, in particular, producing electricity, and covers several sources. First of all, we can talk about the energy of tides that is the result of the gravitational pull of the Moon and the Sun. The energy of waves is another form of ocean energy, and it is linked to the winds and the tides.

Besides, people shouldn’t underestimate and forget about the internal energy of the Earth, I mean, the internal heat of the planet. Geothermal energy has various uses in everyday life, and the experience of Iceland and some other Scandinavian countries proves it. Such energy is pretty suitable for electric power production, heating and cooling houses and other buildings.

Considerable attention should be paid not only to water but also to its separate components, to be exact, one component – hydrogen. This element is one of the most widespread on the planet, and, as a gas, it can’t be found in nature, only in combination with other elements. By the way, once separated it becomes a fuel and can be burned.
