INTRODUCTION:IMAGINE. One day you wake up, and you find the whole world in complete darkness. You try to get out of bed, but you stumble because you are led forth only by your sense of touch. You try to look out of the windows, but you realise you cannot even locate the position of the windows. YOU ARE SCARED, SCARED BY THE WORLD WITHOUT SOLAR ENERGY.
Solar energy refers to the energy that is produced directly by the Sun and collected on the Earth’s surface. The sun creates its energy through a thermonuclear process which converts about 650, 000, 000 tons of hydrogen to helium per second. Through this process, electromagnetic radiation is created and a small fraction of this radiation, called SUNLIGHT, finally reaches Earth.
Today, global warming has become the world's increasing concern as we begin to face changes on an apocalyptic scale. As such, many countries now seek alternative methods of producing electricity, which can reduce carbon emissions. Solar energy is a type of renewable energy that is largely used as it uses resources that can be “renewed” without causing harm to the environment.
In this SIA, we will be focusing mainly on solar energy- what it is, how it is used, why it is considered a form of renewable energy, how green buildings in Singapore make use of solar energy and how it can be further tapped into. -Evelyn
