The amount of energy in an isolated system is conserved eventually, energy can be changed from its original form to a different form are from one object to another. This energy law applies use which is taken energy and changing into a different form, one example is Solar Energy; energy from the sun can be changed in to useable energy for homes, schools, hospitals etc. The energy conservation law also applies to considering that some energy is wasted during the change, it’s impossible to change energy and not waste some of it.
Cons and Pros of fossil fuel and oil, natural gas, and coal are pros consist of higher efficiency, it’s less expensive than none conventional reason being it’s easy to change and process them also has the ability to power the globe, the cons of fossil fuels are they have the biggest emitters of greenhouse gases which is mainly the reason for climate change and global warming. Coal mining creates quakes that’s also believed, they are none renewable so that makes it the biggest con. Nuclear Energy creates small amounts of oxygen and it generates huge amounts of electrical energy. Waste is radioactive when produced in these plants. Uranium is the energy source which has a limited supply; nuclear power plants could encourage terrorist attacks. This source of energy is renewable. Solar energy it provides energy to homes with solar panels and there’s no up keep required most of the energy is produced in the light because the panels become larger, these panels are very costly. Wind power is green and it has no pollution whatsoever, we can’t run out of wind so that makes it renewable and wind can’t be controlled however the disadvantage is the small noise. The energy that is most renewable is Hydroelectricity which is renewable energy that has a lot to spare, its reliable and flexible;
