Future Energy Efficiency Policy (464 KB, PDF)
What is energy efficiency?
Improving energy efficiency means using less energy (such as electricity, heat and transport fuel) to produce the same output or service. Examples of measures to improve energy efficiency include: insulating a home so that it needs less heating to reach the same temperature; installing a motor that uses less electricity to perform the same role in a manufacturing plant; and inflating car tyres to the correct pressure to reduce drag when driving and cut fuel use.
Key points
The key points in this briefing are:
-
The Government will set out future energy efficiency policies and proposals in its Emissions Reduction Plan in early 2017. Future energy efficiency policy choices will also arise from Brexit.
-
Energy efficiency improvements can reduce fuel poverty and greenhouse gas emissions and improve comfort, health, wellbeing, energy security and economic productivity.
-
Barriers to improvements include financial constraints, misaligned incentives, hassle, poor return on investment, lack of prominence and low confidence in results.
-
Regulatory, economic and behavioural policies could improve UK energy efficiency.
-
There is insufficient evidence to identify which types of policy are most effective.

Evolving life sciences and agricultural research approaches may have a decreasing need to access physical resources in future, such as plant seeds or viral material. Information and genetic data may be all that is required for commercial exploitation of biological resources. This POSTnote summarises the challenge this creates for international discussions on the governance of genetic resources and the possible options for addressing these.
