130 exajoules (EJ) per annum for solar photovoltaic and solar thermal electric energy, 110 EJ for wind energy, 40 for hydro, 55 for geothermal and 300 for bioenergy. A closer look at the IPCC summary report on the potential of renewable energy shows that this latter source will remain the leader in primary renewable energy production in 2050. It is two weeks since the Intergovernmental Panel on Climate Change (IPCC) presented its special report on renewable energy and climate change mitigation in Abu Dhabi. One of the first points to come out of reading this report is that bioenergy accounted for almost 80% of the contribution of renewables to primary energy supply in 2008. The next point is that the majority of this contribution, approximately 60%, was from traditional biomass used for cooking and heating in developing countries, although a greater increase in the use of modern biomass was also highlighted. 10% of the 492 EJ of annual primary energy produced in the whole world is generated using biomass, biogas and biofuels. The report warns that this contribution is likely to diminish in the coming decades, although this will not stop bioenergy from continuing as the renewable energy leader, with an average of 150 EJ/year in 2050. Indeed, the IPCC reports even proposes a range of between 100 and 300 EJ, a ceiling that clearly exceeds that of the other five technologies discussed in the IPCC's work: solar photovoltaic and solar thermal electric, hydro, geothermal, wind and marine (tides, waves, currents).

The Fujisawa Sustainable Smart Town (SST) is aimed at reducing CO2 emissions by 70 percent compared with 1990 levels. The completely networked town will be a 19-hectacre subdivision built on a former Panasonic plant site some 30 miles southwest of Tokyo. It will house about 3,000 people whose lives will revolve around being energy conscious: the 1,000 homes and other buildings will have solar panels to generate electricity and smart appliances, as well as home fuel cells. The batteries might include the fridge-sized Ene-Farm developed by Panasonic and Tokyo Gas. They say the Ene-Farm can reduce energy consumption and CO2 emissions by 35 and 48 percent, respectively, from typical Japanese household usage and can help lower home utility costs by up to $740 annually. Plans for the SST call for features such as EV recharging stations, LED lighting, surveillance cameras, and "wind paths" to accommodate wind patterns in Fujisawa, a city of 400,000 on Sagami Bay. There will be plenty of trees, too. The project will cost some $739 million, and all homes are expected to be occupied by 2018. I wouldn't be surprised if SST gets way too many applicants. Fujisawa has beaches, a surfing culture, and plenty of sunshine, so it's an ideal location for this experiment. If it's successful, it could become a model for future green communities.
