Renewable Energy Basics. E-book. Formato EPUB. We often hear about global warming, but only a select few on this planet really understand its full ramifications.
Over the last century, the Earth has witnessed a steady climb in temperatures, revealed in rising sea levels, desert expansions, frequent heat waves, wildfires and melting polar ice caps. And though several natural factors could encourage global warming, the fact remains, that greenhouse gases (GHGs) have been found to be the main culprit. The realization that mankind does directly influence the level of GHGs in our atmosphere, inspires a global call to action!
The United Nations (UN) defines climate change as a long-term shift in temperatures and weather patterns; and it is mostly caused by the burning of fossil fuels. These fossil fuels, are: · Gas. · Coal. · Oil.
GHG emissions caused by the burning of fossil fuels are mainly Carbon dioxide and Methane. When these GHGs are released, they rise to cover the Earth’s surface as a blanket. GHGs don’t pose a problem for the movement of the sun’s heat towards the Earth; However, when the Earth releases heat into the atmosphere as infrared radiation, the GHGs trap the heat around the Earth’s surface, causing global warming due to the rise in temperatures.
To drastically cut down the effects of global warming, emissions into the atmosphere must be reduced. And this can be achieved by a global shift from fossil fuels to renewable sources, for power generation. The importance of renewable energy in the global quest to combat climate change, cannot be overemphasized.
