Today’s topic is a very important one. One that is affecting to every single human being in Earth, even without them knowing it.
But before we get started, first let’s define what is Global Warming.
Global Warming is the gradual increase in temperature of the Earth’s climatic system. It is mainly caused by harmful, uncontrolled human activities. According to experts, 95% of global warming is caused by anthropogenic (human) activities, which leads to concentration of greenhouse gases such as CO2. These form a thickening blanket in the atmosphere that traps sunlight and radiation leading to global warming.
Burning of fossil fuels and use of other non-renewable sources of energy is one of the activities that contributes to this problem. Hence, experts advice that using renewable sources of energy such as wind, solar and hydroelectricity can greatly slow down global warming. These have no effect on the climate, and their sources i.e wind, sunshine and rainfall are naturally replenished on a human time-scale.
But one question still lingers? How do renewable energy sources slow down global warming? Take electricity for example. At the turn of the twentieth century, coal burning was used to power the generator that generated electricity. But since then, hydroelectricity has replaced coal as a cheap, clean and efficient alternative in electricity generation.
Another area is air and water heating. Coal and other fossil fuels were used to accomplish this task, but solar power is now considered the best alternative in heating of air or water. It’s cheap and it’s clean since doesn’t give off any waste gases.
There are many other areas where renewable energy is replacing traditional energy sources. Some include transportation and off-grid energy services. In all these areas, renewable energy sources are preferred because they don’t give off any harmful wastes, which vastly slows down global warming.
Another way to stop global warming is by using less electricity at home. For example, if you have a knife in your kitchen that has lose its edge, you can sharpen it with a manual knife sharpener. But, there are sometimes where you can’t just afford to lose your precious time. If you’re in this case, TheBestElectricKnifeSharpener.com has put a very complete and precise tutorial on how to find the perfect electric knife sharpener for you. There you’ll find information on how to sharpen you knives the right way and also how to keep your knife sharpener clean so that you can always take the most out of it.
