Global energy transformation: A roadmap to 2050 (2019 edition)
Increased use of renewable energy, combined with intensified electrification, could prove decisive for the world to meet key climate goals by 2050. This study highlights immediately deployable, cost-effective options for countries to fulfil climate commitments and limit the rise of global temperatures.
Based on IRENA’s analysis, energy-related carbon-dioxide (CO2) emission reductions would have to decline 70% by 2050, compared to current levels, to meet climate goals. A large-scale shift to electricity from renewables could deliver 60% of those reductions; 75% if renewables for heating and transport are factored in; and 90% with ramped-up energy efficiency.
Alternative heating technologies, such as heat pumps in industries (for low-temperature applications) and buildings, should be promoted.
This is currently my biggest headache. We bought an old house with oil-based heating and I would like to get rid of it as soon as possible. A downhole heat exchanger would be my preferred option. But ideally, this would be used for surface heating like underfloor heating, which is not so easy to realize if you are living in the house already.
