Part 2: Short report on an alternative energy source (5 pts) Research and write a short (1-2 paragraphs) report on an alternative energy source (see list below for ideas) describing: 1. The pros and cons of this energy source (at least 2 of each) 2. The current cost of this energy source per kwh, if available 3. The ability of this energy source to be produced on a large scale 4. At least 2 references Choices of alternative energy sources: Biodigesters, co-generation, tidal energy, landfill gas, biofuels, solar, wind, geothermal, biomass, hydropower, etc. (or a source not listed) Question 6 (5 points) Type your report below. Make sure to identify what your energy source is at the beginning of your report. I will be especially impressed if you find a new alternative energy source!

00:01 Hello students, there are several alternative sources of energy and now we're going to see about one of the examples of alternative energy source and that is the wind energy so now let us see how does this wind energy works? for example now, let us draw a diagram so in this diagram, we could see that a representation of a windmill so when the wind blows suppose the wind blows in this direction and the fan the wind blades the windmill consist of the wind blades and the wind blades rotate so this rotation rotating their blades the blades rotate so this creates a kinetic energy just transformed into mechanical energy and this part that consists of the gearbox spins the generator to produce the electricity so this electricity from the windmill passes down through the cables and just stored in the transformer unit and from there it passes to the sealed transformer from where the voltages get separated and it is transported to the grid for distribution so this is how the wind that blows past the windmill and the blade rotates and the electricity is produced.

02:17 So this wind power is very effective and as the most reliable source of energy that is used widely and this wind power now, let's see the pros and cons of this wind energy so the pros and cons of this wind energy includes the first one they are renewable and clean source of energy they have a low operating cost and when efficient wind energy includes an efficient use of the land space.

03:12 So this is also a pros of the wind energy and now coming to the cons this supply of wind energy is intermittent and some adverse environmental impacts which is very few to be listed and so the adverse environmental impact actually includes that the turbines that is the wind blades they need a safety concerns and there are certain areas like agricultural fields or certain areas the where the windmills cannot be you know placed or where they cannot be constructed and the intermittent that is need be a continuous supply of wind energy and the third con transporting to a very long distances can be expensive so these are the few cons about the wind energy and the second one the cost of the wind energy at present it is about rupees 3 .17 or four dollars per kilowatt hour...
