The Future of Solar Energy

Jun 29, 2017 | 1 comment

Solar energy is becoming an increasingly important form of energy for mankind. Its massive accessibility makes it an exceptional wellspring of power. Utilizing the heat and light emitted by the sun, this power is harness by different kinds of technology, such as man-made photosynthesis, solar heating, solar architecture, molten salt power plants, and photovoltaics.

The said techniques are further divided into two categories. The divisions are the active and passive solar technologies.

Passive solar innovations include the selection of matter that has adequate light dispersing properties, setting up areas that authentically circulate air, and conforming a structure to the sun. Active solar techniques comprise the so-called solar power heating, concentrated solar energy, and photovoltaic systems.

The availability of solar energy

These various technologies are possible because of the abundance of solar energy that the Earth receives. Our planet acquires approximately one hundred seventy petawatts (quadrillion watts) of solar energy coming from the sun. Solar energy emitted by the sun is absorbed by the Earth’s lithosphere, atmosphere, and hydrosphere.

The Warm air containing water vapor from bodies of water rises, causing climatic dissemination or convection. At that point, when the air achieves a high elevation, the temperature will decrease changing water vapor into mists; the moisture will eventually rain onto the Earth’s surface, finishing the water cycle.

The inert warmth of water buildup opens up convection, creating environmental wonders such as twisters and the Cyclones. Sunlight consumed by the seas and land masses keeps the surface at a normal temperature of fourteen-degrees centigrade.

However, topography influences the distribution of solar radiation. The potential solar power that could be utilized by humans contrasts with the measure of solar energy available close to the surface of the planet, because of variables like, time range, geography, and cloud cover. These factors affect the amount of solar power that an area can acquire.

The technologies used in solar energy production

There are three essential advances by which sun oriented energy is typically tackled. Number one on the list is photovoltaics, or PV. It straightforwardly converts light energy into electrical energy.

Second is Concentrating Sun Based Power, or CSP. It utilizes warmth from the sun to drive utility-scale, electric turbines, warming and cooling frameworks, which gather solar power to produce air conditioning and heated water.

The third is the Distributed Generation or DG. It generates power on-site. The gears used are situated on housetops or ground-mounted, where the solar energy is utilized.

The recent developments in solar technology

Analysts have yearned for approaches to enhance the productivity and cost efficiency of the solar cell, because it’s the life of photovoltaic (PV) systems. The solar cells are used in solar photovoltaic clusters involving hundreds of solar cells. These independently transform brilliant daylight into electrical streams.

A normal solar cell is only fifteen percent active, implying an eighty-five percent loss of efficiency. This is the main reason why researchers have always been exploring different avenues for innovations to bolster the current processes for light conversion and absorption.

As of late, a group of researchers at the Toronto University revealed another kind of light-sensitive nanoparticle called colloidal quantum dabs. This nanoparticle, that had been accepted by many, will offer a more affordable and more adaptable material for solar cells.

In particular, the new materials utilize “p” and “n” type semiconductors, that can survive in the outside environment. This is a special disclosure since past application were not useful for the solar market.

Scientists at the College of Toronto found that the n-sort materials tie to the new colloidal quantum dots. These quantum dots do not bond to the O2, supplementing a more brilliant light retention. Boards utilizing this innovation were observed to be eight percent more effective at transforming light energy into electrical energy.

Prospect of solar energy partially replacing fossil fuels in modern day life

The increase in the total energy consumed by the world population is due to two main factors: an increase in the number of developing countries, and the inflation of the global population. More individuals ensure a decrease in the fossil fuels left to be consumed, accelerating the imminent deadline for use of this energy source.

Another contributor is the second and third world countries, because of their steady growth and industrialization that lacks an adequate mastery of energy preservation, resulting in inappropriate energy losses and chemical waste.

Studies concluded that the total world energy consumption and total carbon dioxide will double in the next twenty years. While costs of normal assets are to remain low throughout the following couple of years, if we continue the pattern of expanding worldwide utilization, fossil fuels will undoubtedly run out. The measure of time until this happens, depends upon the endeavors of nations of the world to take advantage of solar power.

Another fundamental reason that countries should change from fossil fuels to solar renewable energy is due to the fact that the discharges of carbon dioxide emission from non-renewable energy sources was 6.2 billion tons during the past couple of years, expanding fourfold compared to the amount emitted during the half of the 18th century. The expanding pattern of CO2 in the air overpowers the regular cycling of carbon by timberlands and seas, and has permitted the growth of CO2 concentrations in the atmosphere. This increase in carbon emissions will result in an increase in worldwide temperatures by around one to three degrees Celsius, causing severe climate change and massive devastation to the environment.In 2011, the International Energy Agency (IEA) stated that new technologies brought by solar energy should imbue a more prosperous future for the seven billion people on earth and its other inhabitants. The advancement of moderate, endless and clean solar energy innovations will have tremendous longer-term benefits. The energy security of nations through dependence on an indigenous, continuous and autonomous asset, that keeps a lower petroleum cost, brings down the expenses of relieving a worldwide temperature alteration, decreases contamination, and upgrades manageability. These points of interest are worldwide. There is presently no question that solar energy will, in the long run, become critical, if not the prevailing source of energy both on an individual, and on an institutional scale. One can dare to dream that the resulting lessening in the need to consume non-renewable energy sources is imminent, and the future of a clean and steady environment is dependent on the utilization of solar energy.

    I know, Solar Energy is FAR from replacing fossil fuels today. But slowly, we’re getting there. I wish more people will fund the development of solar energy.
