    While cable music channels urge their viewers to unplug their cellphone chargers and businesses strive to understand how big their carbon footprint is and how to reduce it, many authorities, city business districts, industrial sites and campuses are already turning to robust, tried and true solutions without waiting for magic-wand policies or revolutionary technologies. This explains why we're seeing renewed interest in district heating and cooling systems around the world.

  • Question: I travel quite a lot, and have seen extensive use of geothermal energy in Iceland and some Eastern European countries for district heating. But, I don't get a sense there is much geothermal use for heating in the United States. Is this the case? If it is, why don't we use more geothermal energy for heating homes and buildings? -- Bill T., Santa Fe, New Mexico

  • A report launched today highlights critical challenges in the current ‘all-electric’ approach to decarbonisation of the UK energy system as this would increase our dependence on the electricity system to unprecedented levels. A system that makes greater use of cogeneration and district heating can however mitigate many of the more demanding aspects of the ‘all-electric’ approach. Used in combination with biomass and CCS technology for fossil fuels, cogeneration and district heating infrastructure have a key role to play up to 2050 and beyond. Find the full report  and the press release here.

    Recently, the District of Columbia became one of the first government organizations in history to publicly promote its system-wide efficiency. The District started to invest in measures to better understand its use of energy throughout its almost 200 public buildings. By energy benchmarking, it hopes to cut back on its use of electricity, natural gas, and other fuels and consequently reduce its greenhouse gas emissions.

  • The proposals launched today outline how those emissions can be reduced both on and off site, including through community scale low carbon heat production for district networks.
  • Non-domestic buildings often have greater potential for onsite renewables (e.g. more roof space) and to play a critical role in the viability of community heat or energy networks.

Honda and Vaillant to launch cogeneration system in Europe - 0 views

    Automaker Honda and German heating and air conditioning specialist Vaillant are joining forces to develop a gas-powered micro-cogeneration system for homes in Europe. Cogeneration heat and power (CHP) systems, which simultaneously produce electricity and heat, are mainly used by industry and in district or community heating schemes. Honda and Vaillant, however, plan to develop systems suitable for detached homes. Honda already offers similar systems in Japan and US, where over 80,000 micro-CHP (MCHP) units have been installed. The new system, which could reduce household emissions by up to 25%, will feature control and connection technology developed by Vaillant with Honda's MCHP unit adapted for the European market.

  • In this ‘green’ future, electricity will comprise 40-70% of energy consumption, up from around 20% now. And a large part of this electricity will come from offshore wind farms, which the report highlights as an economically viable option for Denmark.The Klimakomissionen says many more turbines will have to be erected to cover up to half of the country’s energy consumption.Meanwhile, the energy system will have to become much more flexible and intelligent to cope with the fluctuation of wind energy.Technologies such as smart electricity meters, time-controlled recharging for electric cars and heat pumps in combination with heat storage systems will be crucial to the new energy order.The report says that biomass will play an important role as back up to wind power and to supply heating for homes, along with solar heating, geothermal energy and heat pumps, which will serve district heating systems.

  • From the outside, there is nothing unusual about the stylish new gray and orange row houses in the Kranichstein District, with wreaths on the doors and Christmas lights twinkling through a freezing drizzle. But these houses are part of a revolution in building design: There are no drafts, no cold tile floors, no snuggling under blankets until the furnace kicks in. There is, in fact, no furnace.

    In neighborhoods across the country, there's a battle brewing: the environmentalists vs. the aesthetes. As "green"-minded homeowners move to put in new energy-efficient windows, solar panels and light-reflecting roofs, they are bumping up against neighbors and local boards that object, saying the additions defy historic-district regulations, will look ugly or damage property values.

  • The continued outward growth from a central business district has been the dominant characteristic of most cities in Australia. However, this feature is seen as unsustainable and alternative scenarios to contain the outward growth are being proposed. Melbourne is currently grappling with this issue while simultaneously trying to reduce per capita greenhouse gas emissions. Housing size, style and its location are the three principal factors which determine the emissions from the residential sector. This paper describes a methodology to assess the combined impact of these factors on past and possible future forms of residential development in Melbourne. The analysis found that the location of the housing and its size are the dominant factors determining energy use and greenhouse gas emissions.
