What are the barriers and benefits of greater integration of energy controllers in the household?

Provide DECC with a capability assessment of key energy controllers that will feature in the market in the next 10 years and what control functionality might be available. Estimate potential cost and energy savings when energy using products and their controllers are fully integrated through several different home energy system scenarios. Identify the key barriers to deployment of fully integrated domestic energy systems. Discuss how barriers can be overcome and what the likely timescales might be.
