At a certain location , the solar power per unit area reaching Earth’s surface is 200 W/m square , average over a 24 hours day. If the average power requirement in your home 4.0 KW you can covert solar power to electric power with 13% efficiency. How large a collector area will you need to meet all your household energy requirements from solar energy?
(a) Calculate the power per square meter reaching Earth’s upper atmosphere from the Sun. (Take the power output of the Sun to be 4.00×1026 W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2
reaches Earth’s surface. Calculate the area in
km2
of solar energy collectors needed to replace an electric
power plant that generates 750 MW if the collectors convert
an average of 2.00% of the maximum power into electricity.
(This small conversion efficiency is due to the devices
themselves, and the fact that the sun is directly overhead only
briefly.) With the same assumptions, what area would be
needed to meet the United States’ energy needs
(1.05×1020 J)? Australia’s energy needs (5.4×1018 J)?
China’s energy needs (6.3×1019 J)? (These energy
consumption values are from 2006.)
A typical desktop personal computer uses around 100 W of power when carrying out intensive processing, such as running a video game. If you play such a game for 90 minutes, how much energy (in joules) will it use?

I know that it takes two minutes to bring the temperature of a cup of water from room temperature to just about boiling: ready for the teabag. I looked up the characteristics of a microwave oven. Typically their power rating is about 1000 W, but I know that this is the power consumed from the power company, not the power delivered to the water. I looked up the efficiency of microwave ovens, and found that it is about 64%, meaning that a typical oven delivers 640 W to the water. I also looked up the frequency of the microwaves that an oven uses, and found thatf= 2,450 MHz. (a) How much energy is delivered to the water in the making of a cup of tea?

(d) How many microwave photons are absorbed by the water in making a cup of tea?arrow_forwardSolar panels are rated by their theoretical maximum output capacity.

An energy-efficient fluorescent lightbulb operating at power Pı = 28 W can produce the same level of brightness as a conventional incandescent lightbulb operating at power P, 100 W. Lifetime of the energy-efficient bulb is T = 10000 h, and its purchase price is B1 = $4.50. Lifetime of the conventional bulb is T2 = 750 h, and its purchase price is B2 = $0.42.

Note that you must include both the cost of purchasing the bulbs and the cost of energy.arrow_forward(1) An incandescent light bulb produces 5.85 Joules of light energy each second. This bulb is 7.80% efficient, meaning that only 7.80% the total energy it consumes becomes light and the rest becomes waste heat.
