How energy efficiency is pivotal for reducing carbon emissions?

The author asserts that current national pledges to limit global warming to less than 2°C are insufficient, but doubling the annual rate of energy efficiency improvement could make the COP21 ambitions a reality. A primary lever for this is the transition to LED lighting, which currently accounts for only 10% of the world's 300 million streetlights. A universal switch to LED could reduce lighting's share of global electricity consumption from 19% to 7%, saving €272 billion and reducing carbon emissions by approximately 1,400 megatons by 2030. Beyond environmental impacts, increasing energy efficiency from 1.3% to 3% per year is estimated to create 6 million jobs within five years and reduce the global energy bill by over $2 trillion by 2030. Additionally, off-grid solar LED lighting is presented as a solution for the 1.1 billion people living in light poverty who currently rely on hazardous kerosene lamps and candles.

• While 185 nations have committed to limiting global warming to less than 2°C, the current sum of individual national pledges is not enough to reach this goal.
• Doubling the annual rate of energy efficiency improvement is identified as the mechanism to bridge the gap and achieve the ambitions of COP21, specifically the goal of limiting temperature rise to 1.5°C.
• Lighting represents 19% of global electricity use, but a universal transition to LED lighting could lower this to 7%, resulting in a reduction of global carbon emissions by roughly 1,400 megatons and savings of €272 billion by 2030.
• Increasing the annual progress of energy efficiency from 1.3% to 3% would result in 6 million new jobs over five years and a reduction in the global energy bill by more than $2 trillion by 2030.
• Approximately 1.1 billion people lack access to electric light and rely on kerosene lamps and candles, which cause 1.5 million deaths annually from fires and respiratory illnesses; off-grid solar LED is proposed as a cost-effective solution.
