A contemporary zero-carbon home in England’s East Sussex runs entirely on clean power and generates more energy than it consumes, bringing in a net income of £2650 ($3,300 USD) per year from solar photovoltaics, solar thermal, and a wood-chip biomass boiler. 

Completed in 2011 as a case study, the Lloyd House is a contemporary three-bedroom home that only consumes about half the energy of a typical UK household due to its use of passive solar design, energy efficient appliances, airtightness, south-facing orientation, and effective insulation.

Excess energy is exported to the grid and house emits 93% less carbon dioxide equivalent than the average UK household.
