Promoting Renewable Energy Development
solar power all come from nature directly, so they are called ‘primary energy’. However, it is not easy to transport and use them. Therefore, power plants convert them to electricity, which is convenient to use. Electricity is called ‘secondary energy’. Which kind of renewable energy is not developed in Hong Kong? Why?
Since 2018, the two power companies in Hong Kong have introduced Feed-in Tariff (FiT). Its goal is to encourage their clients to join the companies in using renewable energy to produce electricity. After the clients have installed the solar-energy or wind-energy systems, they can sell the energy they produce to the power companies at a rate higher than the normal electricity tariff rate. This helps the clients get their investment cost back and encourages them to invest in renewable energy.
