District heating is ranked number 27 in Project Drawdown's 100 solutions to global warming. The CMA and other regulators now have the unenviable task of untangling these arguments between Sony and Microsoft and figuring out exactly how this deal could harm consumers or competition. Microsoft still hopes to close this deal out by spring 2023, but there’s a good chance we have months of battles ahead — as well as the opportunity to gain rare insights, as with these mobile plans, into the secret ambitions of the gaming industry. But even if Call of Duty stays on PlayStation, Sony could still lose out on serious revenue if Microsoft offers the title on Xbox Game Pass. Microsoft previously claimed that Sony is paying for “blocking rights” to keep some games off Xbox Game Pass and now says that’s the case with Call of Duty. “The agreement between Activision Blizzard and Sony includes restrictions on the ability of Activision Blizzard to place Call of Duty titles on Game Pass for a number of years,” says Microsoft in its filings.
The European Commission aims to develop sustainable practices through implementation of district heating and cooling technology. Many companies operate district cogeneration facilities that provide steam and/or hot water to many of the office buildings. ADE estimates that 54 percent of energy used to produce electricity is being wasted via conventional power production, which relates to £9.5 billion ($US12.5 billion) per year. Typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. As of a 2007 study, there were 22 geothermal district heating systems in the United States.

Solid majorities across the state’s major regions as well as all demographic groups say the economy is in not so good or poor shape. In a recent ABC News/Washington Post poll, 24 percent (3% excellent, 21% good) of adults nationwide felt positively about the US economy, while 74 percent (36% not so good, 38% poor) expressed negative views. The largest system is in the capital Sofia, where there are four power plants providing heat to the majority of the city. Other European countries are also making great efforts to increase their efficiency. Germany reports that over 50% of the country's total electricity demand could be provided through cogeneration. Germany set a target to double its electricity cogeneration from 12.5% of the country's electricity to 25% by 2020 and has passed supporting legislation accordingly in "Federal Ministry of Economics and Technology", , Germany, August 2007.
A lack of banking options delayed some households from getting federal payments aimed at helping the country weather the economic fallout from the COVID-19 health crisis. Veolia Energy, a successor of the 1887 Boston Heating Company, operates a 26-mile district system in Boston and Cambridge, Massachusetts, and also operates systems in Philadelphia PA, Baltimore MD, Kansas City MO, Tulsa OK, Houston TX and other cities. NRG Energy operates district systems in the cities of San Francisco, Harrisburg, Minneapolis, Omaha, Pittsburgh, and San Diego.

Recent years have seen renewed interest in small modular reactors and their potential to supply district heating. Speaking on the Energy Impact Center's podcast, Titans of Nuclear, principal engineer at GE Hitachi Nuclear Energy Christer Dahlgren noted that district heating could be the impetus for the construction of new nuclear power plants in the future. EIC's own open-source SMR blueprint design, OPEN100, could be incorporated into a district heating system. In most Eastern European countries, energy planning included development of cogeneration and district heating.
Fewer than half of likely voters say the outcome of each of these state propositions is very important to them. Today, 21 percent of likely voters say the outcome of Prop 26 is very important, 31 percent say the outcome of Prop 27 is very important, and 42 percent say the outcome of Prop 30 is very important. The shares saying the outcomes are very important to them have remained similar to a month ago for Prop 27 (29%) and Prop 30 (42%). Today, when it comes to the importance of the outcome of Prop 26, one in four or fewer across partisan groups say it is very important to them.

A large share of DH is produced by small natural gas heat boilers connected to blocks of buildings. In 2014, nearly 40% of the total DH generation was from natural gas boilers, other than co-generation. Direct use geothermal district heating systems, which tap geothermal reservoirs and distribute the hot water to multiple buildings for a variety of uses, are uncommon in the United States, but have existed in America for over a century. The Ågesta Nuclear Power Plant in Sweden was an early example of nuclear cogeneration, providing small quantities of both heat and electricity to a suburb of the country's capital between 1964 and 1974. The Beznau Nuclear Power Plant in Switzerland has been generating electricity since 1969 and supplying district heating since 1984. The Haiyang Nuclear Power Plant in China started operating in 2018 and started supplying small scale heat to the Haiyang city area in 2020.
Heat is recovered using a heat pump and can be sold and injected into the network side of the facility at a much higher temperature (e.g. about 80 ˚C). A modern building with a low-temperature internal heat distribution system can install an efficient heat pump delivering heat output at 45 °C. An older building with a higher-temperature internal distribution system e.g. using radiators will require a high-temperature heat pump to deliver heat output. The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria.
Heat distribution
The association is backed by the key players in the industry including gas and electricity companies, ESCOs, equipment suppliers, consultancies, national promotion organisations, financial and other service companies. They have compiled an analysis of district heating and cooling markets in Europe within their Ecoheatcool project supported by the European Commission. A separate study, entitled Heat Roadmap Europe, has indicated that district heating can reduce the price of energy in the European Union between now and 2050. The legal framework in the member states of the European Union is currently influenced by the EU's CHP Directive. "3. Ability to recycle heat from low-temperature sources and integrate renewable heat sources such as solar and geothermal heat." Microsoft’s Activision Blizzard deal is key to the company’s mobile gaming efforts.
Results for other racial/ethnic groups—such as Native Americans—are included in the results reported for all adults, registered voters, and likely voters, but sample sizes are not large enough for separate analysis. Results for African American and Asian American likely voters are combined with those of other racial/ethnic groups because sample sizes for African American and Asian American likely voters are too small for separate analysis. We also analyze the responses of likely voters—so designated per their responses to survey questions about voter registration, previous election participation, intentions to vote this year, attention to election news, and current interest in politics. As Californians prepare to vote in the upcoming midterm election, fewer than half of adults and likely voters are satisfied with the way democracy is working in the United States—and few are very satisfied. Satisfaction was higher in our February survey when 53 percent of adults and 48 percent of likely voters were satisfied with democracy in America. Today, half of Democrats and about four in ten independents are satisfied, compared to about one in five Republicans.
"Fortum and Microsoft announce world's largest collaboration to heat homes, services and businesses with sustainable waste heat from new data centre region". During Roman times, warm water was circulated through open trenches to provide heating for buildings and baths in Pompeii. In Helsinki, an underground datacenter next to the President's palace releases excess heat into neighboring homes, producing enough heat to heat approximately 500 large houses. A quarter of a million households around Espoo are scheduled to receive district heating from datacenters. Individual heating systems can be completely shutdown intermittently according to local heating demand which is not the case with a district heating system.
The largest district heating system in Austria is in Vienna (Fernwärme Wien) – with many smaller systems distributed over the whole country. Since nuclear reactors do not significantly contribute to either air pollution or global warming, they can be an advantageous alternative to the combustion of fossil hydrocarbons. However, only a small minority of the nuclear reactors currently in operation around the world are connected to a district heating network. These reactors are in Bulgaria, China, Hungary, Romania, Russia, Slovakia, Slovenia, Switzerland and Ukraine. Based on the above description it is clear that there is a fundamental difference between the 5GDHC and the prior generations of district heating, particularly in the individualization of the heat generation. "4. Ability to be an integrated part of smart energy systems (i.e. integrated smart electricity, gas, fluid and thermal grids) including being an integrated part of 4th Generation District Cooling systems."
A primary motivation for building these systems was security of supply by improving the energy efficiency after the two oil crises led to disruption of the oil supply. Therefore, those systems usually used coal, biomass and waste as energy sources, in preference to oil. In some systems, geothermal energy and solar energy are also used in the energy mix. For example, Paris has been using geothermal heating from a 55–70 °C source 1–2 km below the surface since the 1970s for domestic heating. The common medium used for heat distribution is water or superheated water, but steam is also used. The advantage of steam is that in addition to heating purposes it can be used in industrial processes due to its higher temperature.
District heating requires a long-term financial commitment that fits poorly with a focus on short-term returns on investment. Benefits to the community include avoided costs of energy through the use of surplus and wasted heat energy, and reduced investment in individual household or building heating equipment. District heating networks, heat-only boiler stations, and cogeneration plants require high initial capital expenditure and financing.

"Waste heat" from this process is recovered for distribution through the 11 km mains network. The second generation was developed in the 1930s and was built until the 1970s. It burned coal and oil, and the energy was transmitted through pressurized hot water as the heat carrier. The systems usually had supply temperatures above 100 °C, and used water pipes in concrete ducts, mostly assembled on site, and heavy equipment. A main reason for these systems was the primary energy savings, which arose from using combined heat and power plants.
In 1890, the first wells were drilled to access a hot water resource outside of Boise, Idaho. In 1892, after routing the water to homes and businesses in the area via a wooden pipeline, the first geothermal district heating system was created. The heat produced by nuclear chain reactions can be injected into district heating networks. This does not contaminate the district pipes with radioactive elements, as the heat is transferred to the network through heat exchangers. It is not technically necessary for the nuclear reactor to be very close to the district heating network, as heat can be transported over significant distances with affordable losses, using insulated pipes.
