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
