The British government’s policy of incrementally upgrading energy efficiency in UK homes is not enough to meet the country’s 2050 climate targets. Instead, virtually every UK house needs a one-off retrofit, says a new report. It calls for government and cities to commit to pilot schemes for retrofitting whole houses using models such as the Dutch “Energiesprong”, which achieves a near net-zero energy home, typically by adding external insulation … [Read more...]
Smart cities: not enough projects make the grade
Despite the hype about smart cities, and the availability of EU funding, there are very few projects out there that qualify for funding, according to Lada Strelnikova, lead fund manager at the European Energy Efficiency Fund (EEEF). An exception: Belgian bank Belfius has, with the support of the European Investment Bank (EIB), provided €1 billion to smart city projects involving more than 100 municipalities in Belgium. According to Joost Declerck … [Read more...]
Replacing copper with negawatts—how the UK’s RIIO-2 could revolutionise network regulation
Ofgem’s recent framework decision on improving its performance-based regulation scheme, RIIO, indicates that it may be ready to take a much-needed step toward levelling the playing field between supply-side and customer-side resources. However, it is not yet clear what the details will look like. According to Jan Rosenow of the Regulatory Assistance Project, a global group of regulatory experts, Ofgem should put a network regulation scheme in … [Read more...]
Stop worrying about how much energy bitcoin uses
Bitcoin mining is criticized because it uses a lot of energy. But according to Katrina Kelly-Pitou of the University of Pittsburgh, this should be put in context. Many new technologies use large amounts of energy. The important point is how carbon-intensive its energy use is. That depends on where the mining takes place. Courtesy The Conversation. … [Read more...]
Reducing U.K. home energy use by 25% is not “too difficult”
Some energy specialists believe that “all the easy stuff on energy efficiency has been done”, but Jan Rosenow of the Regulatory Assistance Project (RAP) disagrees. New research shows that one-quarter of the energy currently used in U.K. households could be “cost-effectively” saved by 2035, he writes. But it can’t be done without policy support: the government will have to recognise the broader social benefits of energy efficiency investments, … [Read more...]
How rapidly can we transition to 100% renewable electricity?
Science tells us that, to avoid devastating climate change, we must rapidly cut greenhouse gas emissions to zero. How fast is possible, asks Mark Diesendorf of the Cooperative Research Centre for Low Carbon at the University of New South Wales (UNSW) in Australia. He believes the sceptics may be wrong. … [Read more...]
Europe aims to have 300 smart cities by end of next year
With the help of the Smart Cities and Communities European Innovation Partnership (EIP SCC), 78 cities in Europe have undertaken smart city development. The EIP-SCC aims at a critical mass of 300 smart cities by the end of 2019, according to Andreea Strachinescu of the European Commission. The most difficult part, she says, is not the renovation of individual buildings, but the systems integration. The next step: positive energy districts. … [Read more...]
