- Book: Sustainable Energy, Si Edition, 2nd Edition by Richard A. Dunlop Chapter 16 - Problem 1. How many tonnes of wood per day would be needed for a wood-fired generating station that produces 1,000MW continously (typical of a coal-fired facility) at 35% efficiency?A 2.0 m2 solar panel is fully illuminated by sunlight. Assume the sunlight has a power density of 0.10 J/cm2 -s. a) If the efficiency of the solar panel is 16%, how much electrical energy will it deliver in one hour? b) If this energy is stored in a battery, how long will it keep a 100 W incandescent lightbulb burning if the bulb has an efficiency of 2.6%. (Efficiency of the lightbulb is the light out - - 100 W - to the electrical power in.)Write some background information about MOFs energy conversion and storage. Write about past and current technologies, innovations, implications. Use three reliable sources
- 3. A container 50 ft by 100 ft by 20 ft deep is half-filled with a liquid (filled to a depth of 10 ft). How much work is done in pumping all the liquid out of the container to a height of 2 ft above the top of the container? (The liquid's density is 60 lb/ft³.) Your answer should include units.Geothermal energy uses the subsurface level of the earth to heat up water converting it to steam and then using the steam to turn a turbine attached to a generator to generate electric energy. If the geothermal energy conversion process is 46% efficient and there was 789 J of electricity produced, how much energy did the steam have before reaching the turbine? answer 1715 eff=output/inputx 100Wind and solar power are both considered renewable sources of energy. Although they are not as widespread as fossil fuel generators, they are slowly gaining popularity worldwide. a) How does a wind turbine generate electricity? b) How does a solar cell generate electricity? c) What common disadvantage do these two methods share? d) If you had to choose between installing equivalent capacity solar cells or wind generators at your home, which one would you install?
