Energy efficiency makes the biggest impact on C02 emissions

New research from the International Energy Agency (IEA) has shown that energy efficiency is the biggest driver of reducing global C02 emissions, the Huffington Post has reported.
 
According to the IEA's statistics, energy efficiency can deliver more than a third (38%) of the reductions needed to keep the Earth within two degrees of global warming by the year 2050. As such, the article notes that it should be top of the agenda for any policies and discussions regarding climate change.
Of course, the technologies and solutions required to improve energy efficiency within buildings already exists, and it makes good financial sense for businesses.
 
The building sector makes up around a third of global energy usage, and by the year 2040 it is expected to contribute an impressive 45% to C02 emissions that relate to energy efficiency. This is partly because building codes will become even stricter, as will energy performance standards for heating equipment and appliances.
 
Technologies also play a key part in the building sector's role, including intelligent heating systems, radiator thermostats and advanced variable-speed compressors.
 
Industry, which currently accounts for 40% of global energy output, also stands to gain a lot from improving its energy efficiency. By 2040 it is estimated that industry will contribute to more than a fifth (21%) of energy-related C02 emissions. Fitting industrial motors with variable speed drives, for example, can reduce consumption by as much as 40%; yet the majority (70-80%) of new industrial motors throughout the world are not fitted with them.
 
As well as all this, renewable energy sources can be integrated into smart energy systems to improve energy efficiency even further. From supermarkets to factories and entire district energy networks, energy can be stored and used on a supply and demand basis, according to the renewable sources available.
 
While this all sounds like a step in the right direction, the article highlights the key problem that now needs to be dealt with: that adoption rates of these technologies remains slow. According to IEA predictions, just one third of energy efficiency's potential can be met under current policies, even though its impact on climate change is vast.
 
Therefore, the publication advises that world leaders should encourage and perhaps even enforce the increased uptake of energy-efficient solutions, and create global frameworks to help overcome hurdles such as funding and education.
