Z.V.C Coal<br />Our company makes Coal Energy that turns into Electricity that supports your home that you live in right now. So it’s up to us to make Electricity.<br />
Hear AboutUs<br /> Zianne Lopez, Valeria Barboza, and Colleen Carlin are founders of Z.V.C Coal. <br /> All three of us graduated from Harvard University we also got our PHD in engineering.<br />Presidents of Z.V.C Coal, we also play part in making the coal electricity for your homes.<br />
Coal<br />Coal is a fossil fuel because they have been formed from organic and prehistoric plants and animals.<br />Burning fuel makes hot water to make steam and then steam turns into turbines then turbines turn generators that then turns into electrical energy. <br />
Advantages of Coal<br />-Cheap<br />-Large amounts of electricity can be generated<br />-Transportation is easy<br />-Very efficient <br />-Can be built almost anywhere<br />
Disadvantages of Solar<br />-Doesn’t work at night<br />-Expensive to build solar power stations<br />- Unreliable unless in sunny climate<br />
Disadvantages of Hydroelectricity <br /> - dams are expensive to build<br /> - causes upstream to get flooded and rewinds animals homes<br /> - water quality and quantity downstream can be affected <br />
Disadvantages of Wind Power<br /> - can kill birds<br /> - wind is not always predictable <br /> - can be noisy<br /> - some people feel that covering the landscape <br /> is unsightly<br />
Disadvantages of Wave Power<br />-Depends on waves sometimes lots of energy sometimes none <br />-Needs a suitable site<br />-Sometimes designs are noisier than the waves<br />-Has to be able to withstand rough weather <br />
Disadvantages of Bio Gas<br />-When we burn it makes greenhouse gas just as fossil fuels do.<br />
