There are three laws to thermodynamics. These laws affect our everyday life and you probably aren’t even aware. The first law is my favorite and most intriguing law. That’s because it keeps you tracing back energy to the beginning of time. I’ll explain briefly the first two laws of thermodynamics. The first law of thermodynamics states that energy cannot be destroyed nor created. It can only be transferred or converted. An example of how it’s applied to human life would be electricity. The computer im using to write this or you to read this is run by energy. The computer itself isn’t made of energy. The energy or electricity was transferred from somewhere else. The first law of thermodynamics basically explains that this energy had to …show more content…
It’s to conserve more energy, cut costs and sustain what little resources left on earth. There are many different energy types used by mankind. One main energy source are fossil fuels. The most known fossil fuels are natural gas and coal. Fossil fuels are used all around the globe to power our vehicles, lights, factories and much more. The big question is are they safe or cause more harm than good? We all know about global warming and how harmful fossil fuels can be. We have found different alternatives to fossil fuels which include wind, solar and hydro power as I’ve explained a little earlier. Wind power is the most self-explanatory source of energy. Wind energy which is produced by the sun is used to turn turbines that transfers it down the line to our homes. Wind doesn’t cause pollution and we can’t run out of it. The problem is wind is intermittent and isn’t a stable source to power society as a whole. Solar energy seems pretty self-explanatory which it is. Solar companies install panels on your rooftop to capture the sun’s energy. It channels it through some wires to an inverter. The inverter converts the solar energy to electricity to power your home. If somehow the solar power system produces more power than needed it’ll feed it back to the electricity grid. Nuclear energy originates from heat generated by splitting uranium atoms through fission. The product of said fission would be steam. The steam is used to power turbines similar to wind power.
