SOLAR

Solar cells harness light and heat from the sun and convert them into energy. Solar power has been touted as the most promising source of renewable energy for Singapore.

However, it accounts for less than 1 per cent of the electricity consumed here, due to high costs and land constraints in installing solar panels. The Government aims to make it 5 per cent by 2020.

Take its SolarNova programme, which aims to increase solar demand across government agencies. Under the scheme, the Housing Board has committed to a target of 220MW, by generating power through solar panels at 5,500 blocks.
