Use of solar energy is near a solution

This headline in the New York Times on the 4th of April 1931 turned out to be a premonition and now nearly a century later renewable energies and in particular solar are supplying electricity to millions of people around the world.

Development of solar energy is impossible to ignore the Sun shines on our planet continuously and in one hour provides enough light and heat to fulfill our global energy needs for a whole year. Solar radiation can satisfy our total day to day energy needs 4000 times over.

According to NASA our Sun has a lifespan that will last for another 6.5 billion years.

The main benefits of solar energy are that it is renewable, inexhaustible and is non-polluting. It reduces our dependance and use of fossil fuels therefore avoids global warming.

When PV technology first began it was used in the space industry to power satellites. According to the Spanish Association of Renewable Energy Producers  PV development accelerated in the 1950’s and has now become a viable alternative to fossil fuels. PV Systems are a non-polluting and inexhaustible source of electricity and as well as providing electricity to our towns and cities they are an effective solution in remote and rural areas where the normal supply of electricity via the network is not possible. 

Since the 1980’s the cost of solar technology has been falling at around 10% per year and over the next decade this form of energy will become the cheapest source of electricity in many parts of the world.

Industry experts estimate that by 2027 the technology will be able to provide 20% of global energy requirements.

In the domestic renewable world Photo Voltaic panels convert sunlight and day light into electricity to run household appliances and lighting. Commonly known as PV panels. These photovoltaic cells do not rely on great amounts of sunshine and can produce energy at a reduced amount even on a cloudy day. 

PV cells are made from layers of semi conducting material usually silicon. As light shines on the cell the layers create an electrical field between them and the stronger the light or sunlight the greater the amount of electricity produced.

Groups of the cells are incorporated into modules that once assembled form the panels that we all recognise. They can be mounted anywhere but normally form part of a roof installation to gain maximum generation of electricity.

The energy generated is measured by  kWp (kilowatt peak). The point at which the panel is working at its optimum in a good amount of direct sunlight.

With the roll out of electric smart meters here in Spain domestic PV systems are really worth considering as a green alternative. Domestic PV systems at certain times will generate surplus electricity which via the smart meter is returned back in to the grid. The amount of electricity sent back is recorded and the supplier Iberdrola for instance recognises this and duly offsets the amount which is subsequently deducted from the monthly bill. Therefore these systems not only provide a free green alternative source of renewable energy you can get rebates on the surplus electricity you do not use.

 

10% growth

In 2019 Spain experienced a growth of 10% in the non-polluting installed power capacity (green energy production). Simplified 5,000 new megawatts of electricity were generated using green technologies. In context renewable energy in Spain now represents 49.3% of total amount of electricity generated which stands at 108,000 MW of this solar PV accounted for 7,800 MW.

The increase in renewable energy supply is assisting in the decarbonisation of Spain not only because of the installation of new renewable generation capacity but also as a result of the closure of the Anllares coal-fired power station in León, which reduces 347 MW of fossil fuel polluting power generation.

 

To summarise.

The New York Times article put forward the suggestion that Humanity “will no longer have to fear the exhaustion of coal reserves foreseen within the next few hundred years, if Dr Lange’s theory is right”.

Well, the words of German solar energy scientist, Dr Bruno Lange, back in 1931, have been proven right.
