The International Panel on Climate Change (IPCC) gave a stark warning that temperatures are rising across the world. The IPCC estimated that if no further action to reduce CO2 was taken temperatures would increase by 1.5 degrees centigrade within 11.5 years. It is regarded by may as the point of no return. Ice caps melt, sea levels rise, the planet gets warmer because of increasing CO2 and other greenhouse gases. This impacts all our lives. In this episode of Finding Out we look at the ways in which we heat our homes. In the United Kingdom 23 million homes rely on Natural Gas which produces CO2 as a byproduct. Two main alternatives have been considered to reduce CO2. The first is using a heat pump to push natural heat captured from the environment around the home. The second is to use Hydrogen as the energy source which produces only water as a byproduct and is far less harmful than Natural Gas. However, both proposed alternatives incur greater capital cost to install into existing homes.
