The Solar energy is coming to the earth in the shape of electromagnetic radiation from the sun, which has been generating by a progression of nuclear fusion. The employ of solar energy can be done in two methods: by high temperature thermal conversion and by the mean of photovoltaic conversion. For some time at the present, universal energy marketplaces are continually changing, but this time they have reached a tricky milestone.
The thermal exchange of high temperature is to alter solar energy into thermal energy stored in a fluid. Devices called manifolds are used to heat the liquid.
The photovoltaic conversion has in the direct transformation of light energy into electrical energy. Solar panels shaped by photovoltaic cells are used for this.
Advantages of the solar energy: It is a non polluting energy and offers cheap energy in non-industrialized nations compare to electrical energy.
Solar energy is becoming thanks to new emerging markets in the cheapest way to obtain electricity. Although the new reality could be intuited according to some experts in the field, the surprise is that it has occurred so soon.
Solar Energy is cheaper than Electricity
There was already evidence that solar energy at some particular time in the past had been cheaper to produce than Electricity, but always in exceptional and very specific cases, attending especially competitive tenders such as in the Middle East.
However, now the change is more radical, if we look at the new facilities they are competing forcefully with natural gas or coal worldwide, in fact, at quite lower prices depending on what sites.
Why there is a great growth of renewable in emerging countries
Emerging countries are growing far more than the world’s first economies in renewable energy. That why these most of developing countries are adopting the concept of solar energy.
If we look at the total investment in renewable energy, emerging markets have taken the lead over the 35 member countries of the Organization for Economic Cooperation and Development (OECD), spending $ 154.1 billion in 2015 compared to $ 153.7 billion in those richest countries.
Renewable energy growth rates are higher in emerging markets, so they are likely to remain renewable energy leaders indefinitely, especially now, where 75% of countries have set ambitious goals for installing new renewable projects in the next years.
What could change solar energy?
And let’s not just talk about money or promises of the future: solar energy proposes real and immediate solutions. There are some of its advantages:
- Facades of buildings in urban centers that are photovoltaic panels, so that the electrical consumption of the same is self-generated and does not increase public spending , from security cameras to the coffee machine. The Pearl River Tower is one of many examples.
- Heaters, electric fences and automatic livestock systems. In many industrial farms diesel generators are used. This invasive excess environmental noise seriously worsens the health of animals. With photovoltaic panels the problem disappears.
- Toy industry Toys where part of its outer covering is its own electricity generator. Like calculators or kitchen weights, they never deplete their energy, are safer and drastically reduce the environmental footprint left by traditional galvanic batteries, where only one, based primarily on zinc, manganese dioxide and iron oxide (or coal) , they can contaminate up to 3,000-3,500 litters of water.
- Drinking water pumps, beacons, treatment plants or desalination systems. Where the traditional electricity industry does not arrive due to a strict need for infrastructure, photovoltaic panels can solve these consumption needs.
