Solar energy

The frightening effects of climate change are driving the world's citizens to develop and implement clean energy sources. The burning of fossil fuels is the clear cause of global warming but fortunately, the world's supply of these dangerous substances in nearing an end. But scientists recognize that we need to quickly transition to alternative energy sources as rapidly as possible to slow the dangerous effects of climate change. Renewable sources of energy such as solar power are revolutionizing the energy market. but solar is certainly nothing new. It's just that new technologies are making solar more affordable for more home and business owners.

Humanity has now declared its sincere intent to accelerate the transition to a low-carbon economy, conscious of the limited nature of fossil fuels and their toxic effects on the environment as the main cause of global warming.

Solar energy is on the rise all over the planet

Solar energy will never stop shining since the Sun still has 6.5 billion years of life according to scientists. Indeed, in rather short time, solar technology in many countries has evolved to compete with conventional sources of electricity generation. In just a few decades, it will become the major component of a sustainable energy system for the entire world. Additionally, the conditions for the deployment of solar energy could not be more perfect: the sun bathes the earth hourly with enough light and heat to fulfill global energy requirements for a whole year.

As the publication, Renewable Energies Info estimates, the Earth’s surface receives 120,000 Terawatts of solar "juice", “which represents 20,000 times more power than the whole planet needs. Supporting this argument further, the Union of Concerned Scientists reports that as little as 18 days of solar irradiation on earth contains as much energy as all the world’s coal, oil and natural gas reserves combined together.

What is solar energy?

Solar power is energy produced by the sun’s light for the generation of electricity or the production of heat. Solar energy is Inexhaustible and renewable, since it comes from the sun, and is harnessed using panels and mirrors. Photovoltaic solar cells convert sunlight directly into electricity by the photovoltaic effect, by which certain materials are able to absorb photons (light particles) and liberate electrons, producing an electric current. However, solar thermal collectors use panels or mirrors to absorb and concentrate the sun’s heat, transferring it to a fluid and conducting it through pipes to use in buildings and installations, and also for electricity production (solar thermoelectric).

What are the prime benefits of solar energy?

Solar energy provides many benefits that make it the most promising energy forms. Renewable, non-polluting, and available planet-wide, solar contributes to sustainable development and job creation where it is installed.

SUMMARY OF THE BENEFITS OF SOLAR ENERGY

Renewable

Inexhaustible

Non-polluting

Avoids global warming

Reduces use of fossil fuels

Reduces energy imports

Generates local wealth and jobs

Contributes to sustainable development

How is solar energy generated?

The sun provides energy in two different ways: It provides heat tapped by mirrors that focus sunlight on a receiver that contains a fluid which reaches temperatures up to 1,000 ° C. The heat transforms the fluid into steam which spins a turbine and finally produces electricity. It provides light that is converted into electricity through photovoltaic solar panels. Photovoltaic panels are formed by groups of cells or solar cells that convert light (photons) into electrical energy (electrons). The rapid expansion of solar energy production helps motivate the technological advances that are making solar panels cheaper and more effective.
