Energy demand for cooling in the OECD was higher than in non-OECD countries in 2010. In our New Policies Scenario, not accounting for climate change, global energy demand for space cooling already gro... ws by nearly 145% to 2035 and is around 175% higher by 2050, pushed largely by demand from emerging markets in Asia, primarily China. However, climate trends are going to change over the coming decades and, once these are taken into account, the results show that global energy demand for space cooling increases by around 170% to 2035 and 220% by 2050, compared with 2010 levels. In 2050, energy demand for cooling is significantly higher in non-OECD countries than in the OECD. In non- OECD countries demand increases by nearly 400% (105 million tonnes of oil equivalent "Mtoe") compared to around 60% (20 Mtoe) in the OECD by 2050. The largest absolute change in energy demand for cooling is in China, where the effect of increasing incomes (boosting ownership of air conditioners) is complemented by increased cooling needs as a result of rising temperatures. In relative terms, the biggest change in cooling demand that occurs as a result of climate change (i.e. a comparison between our New Policies Scenario results with and without climate change) is in China, followed by the United States, the Middle East and India (Figure 3.3). All of the increase in energy demand for cooling in the residential sector is in the form of electricity, which can be challenging for power system stability during extreme heat waves. Note: These regions cover almost three-quarters of the global energy consumption for space cooling.
