HOW PUSHING WATER UPHILL CAN SOLVE OUR RENEWABLE ENERGY ISSUES

摘要

More and more renewable energy sources are being plugged into Australia's electricity grids. South Australia, for example, will get 40 per cent of its electricity from wind and solar once the Snowtown wind farm is completed later this year. But if renewable energy is ultimately to dominate the market, we will need ways to store the energy so we can use it round the clock. The good news is that it is easy to store energy. All you need is two small reservoirs - one high, one low - and a way to pump water between them.
