ri Lanka will today launch a powerful move in the battle against climate change, with the installation of renewable solar energy equipment at President Maithripala Sirisena’s private residence amid rays of hope, that about one million households will have solar energy within months.
The Power and Energy Ministry’s creative and innovative project is already being promoted and launched in the Trincomalee, Ampara, Jaffna and Hambantota Districts. The installation fee could be paid by the households in installments and it would be deducted through their monthly electricity bills to streamline the procedure. In addition, those who cooperate with this eco-friendly move, will be given a reduction in their electricity bills for their house sections, which still obtain electricity.
Most people are reluctant or afraid to change from known procedures, but we need to realise now that the world is changing faster than ever before with digital automation, globalisation and the latest report that the Massachusetts Institute of Technology (MIT) has created a social robot that has Emotional Intelligence and could communicate with people.
Sri Lanka being a tropical paradise, we have solar power for at least 12 hours of the day every day of the year, unlike some countries where long winters give them only a little sunshine or access to solar power during those months.
From the beginning of time, sunlight or solar power has been freely available to anyone who accepted it. The world, now facing an ecological catastrophe due to climate change and environmental pollution, has only now become fully aware of the need to harness solar energy to the maximum.
This energy is renewable and causes little pollution and is also less costly than hydro-electricity, coal power or any other source.
According to astronomers our Sun is one of more than 100 billion stars in our galaxy. The sun’s diameter is 1,390,000 km and its surface temperature 5,800K, a unit of measure for temperature based on the Kelvin Scale.
In the core the sun is 15,600,000 K. It is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System.
According to the National Geographic Magazine every hour the sun beams onto earth more than enough energy to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun’s energy and make it useable. Today, technology produces less than one tenth of one percent of global energy demand.
Many people are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and hand-held calculators. The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity.
On a much larger scale, solar thermal power plants employ various techniques to concentrate the sun’s energy as a heat source. The heat is then used to boil water to drive steam turbines that generate electricity in much the same fashion as coal or nuclear power plants, supplying electricity for thousands of people.
The National Geographic says solar energy is lauded as an inexhaustible fuel source that is pollution and often noise free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in the orbit of the Earth and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and future vehicles.
