The sun doesn't shine as brightly in winter as it does in summer. This means that in winter you won't generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. Question: How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures (link). Remember we use 2990 kWh of electricity per year. Write down your answer as you need it for the next question Solution: kWh

Question: Calculate the Solar Energy potential (GWh) that can be generated on Annual Basis if 50,000km2 of the area of Jordan was covered with Solar PV modules. List your assumptions: Solar PV estimated generation = 2GWh/MWp Each 1MWp will need = 10,000m2 Cost of fossil fuel to generate electricity in Jordan = 1000 million JD/year Annual Electricity Generated in Jordan = 20,000 GWh Required Calculate Solar Energy potential by Dividing the Electricity generated from PV over 50,000km2 / Annual Electricity Generated? You are going to Build a Solar PV Plant to cover the Annual Electricity Needs of Jordan What is the Size of the plant? Calculate Present Value (P), if the cost of the 1MWp = 500,000JD. If the cost of Generation of Electricity in Jordan is 0.10JD/KWh, what is the Simple Payback Period (SPP)? What is the annual electricity saving (A0) if the degradation is 1%? What is (A1) if the operation, maintenance and cleaning is 2% of initial cost? What…
The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?
Why do we say energy cannot be created or destroyed? Isn't energy created in a light bulb?
A toaster has a power rating of 732 watts. If it takes 1.1 minutes to toast a slice of bread, how many joules of energy are required? Round your answer to the nearest whole number. The energy required would be Joules.
What is the greatest energy? a) The kinetic energy of a 1000 kg car travelling at 100 km/hr. b) The heat required to raise the temperature of 1 kg of water from 15°C to 45°C. c) The energy contained in 200 g of butter. (The energy content of butter is 25 kJ/g.) d) The energy required to convert 300g of liquid water at 100°C into steam.
Jason is investigating how energy from the Sun drives convection in the atmosphere. He wants to draw a diagram showing what happens to air when it is heated by the Sun during the process of convection. Which diagram should he draw? A He should draw a diagram that shows cool air in Earth's atmosphere rising. B He should draw a diagram that shows cool air near Earth's surface rising. C He should draw a diagram that shows warm air in Earth's atmosphere sinking. D He should draw a diagram that shows warm air near Earth's surface rising.
A 400 kg satellite is in a circular orbit at an altitude of 425 km above the Earth's surface. Because of air friction, the satellite eventually falls to the Earth's surface, where it hits the ground with a speed of 1.80 km/s. How much energy was transformed into internal energy by means of air friction? Need Help? Read It
bacon-cheddar-double-burger meal along with A 65.0-kg mountain climber just ate a Johnny Rocket's two peanut butter milkshakes, which have 5810 Calories (5810 kilocalories). Assume she can convert these calories into energy with 100% efficiency and use the fact that 1 kcal = 4186 J. Calculate how many times she could climb up Mt. Everest - the world's tallest mountain. The height of Mt. Everest is 8840 m.
A person eats an 408.85 J snack before working out. If a person uses all of their eaten energy to lift a 10.36 kg weight. How high can they lift the weight?
A 150-pound hiker walks at 3 mph up a 5% slope. This incline is a ratio of the vertical distance and horizontal distance expressed as a percentage (for example, the vertical distance increases by 5 feet for every 100 feet horizontally). What metabolic power is needed for this hike? (Hint: Model her power as a sum of the power needed to walk on level ground and the power needed to raise her body the appropriate amount).
