Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
Household actions lead to changes in collective behaviour and are an essential part of social movements.

Households generate a large share of national greenhouse gas emissions and can take steps to reduce them.
The next 20 years of Britain’s electricity policy must look very different from the previous 20.

Due to inefficiencies in global energy systems, energy falls short of even making it to the consumer, often lost in the form of waste heat.
Projections are often be repeatedly wrong. That’s because the models don’t learn from mistakes.

From wage growth to renewable energy to religion, projections are being treated as predictions. We’d be better off insisting on genuine forecasts.
