since 2015, the installed capacity of new energy and renewable energy in beijing has increased by 101.2%, accounting for 20.8% of the total installed power generation capacity. through the "beijing green life platform", 6.7 million citizens have established "personal carbon ledgers". this is the data learned by reporters at the exhibition area of beijing energy conservation and environmental protection center at the 2024 services trade fair.
at this services trade fair, the beijing energy conservation and environmental protection center set up a "capital green development and innovation practice exhibition area", which demonstrated the innovative practices of the beijing energy conservation and environmental protection center in supporting and promoting the comprehensive green transformation of the capital's economic and social development through sand tables, real objects, models, videos, exhibition boards and other forms.

green beijing city, this year's green electricity trading islast year7.5 times the same period
in the exhibition area of beijing energy conservation and environmental protection center, a huge green sand table is particularly eye-catching. on the sand table, various projects such as wind power, photovoltaics, and biomass power generation are scattered.
according to reports, in recent years, beijing has vigorously developed new energy and renewable energy, and has successively built and put into operation a number of new energy and renewable energy projects such as wind power, photovoltaic, and biomass power generation. as of the first half of 2024, more than 1,000 enterprises and institutions and 30,000 households have installed photovoltaic power generation systems. the scale of new energy and renewable energy installed capacity in beijing has increased by 101.2% compared with 2015, accounting for 20.8% of the total installed power generation capacity. beijing has also continuously expanded the "circle of friends" of green electricity sources to enrich green electricity sources and ensure green electricity supply.
on the consumption side, beijing consumed 19.76 billion kwh of green electricity in the first half of the year, accounting for 29.4% of the total electricity consumption in the society, an increase of 17.9% over the same period last year. the scale of market-based green electricity transactions in the first half of the year reached 4.05 billion kwh, 7.5 times that of the same period last year. many typical application scenarios such as the administrative office area of the sub-center of the city, the state grid future science city park, and the self-operated charging piles of the bus group have realized full green electricity application.
the "urban green heart" in tongzhou was also made into a sand table and displayed at the services trade fair. according to reports, in addition to green development projects such as ecological governance and green building construction, green energy is also a major feature of the urban green heart. the three major cultural facilities of the "urban green heart" all use a composite solution of "ground source heat pump + water storage + chiller + gas boiler" for cooling and heating. in addition, the park also realizes the comprehensive utilization and promotion of green energy by installing rooftop photovoltaic and energy storage facilities, building a smart distribution network, and piloting green electricity and green certificate trading.
green new technology, beijing has recommended 244 energy-saving technology products
the development of science and technology is an important driving force for green transformation and development. according to reports, since 2020, beijing has continued to organize and promote innovative green technologies and energy-saving technology products. so far, a total of 142 innovative green technologies and 244 energy-saving technology products have been recommended. on the occasion of the 10th anniversary of the coordinated development of beijing, tianjin and hebei, 19 typical cases of green and low-carbon technologies in beijing, tianjin and hebei were released for the first time. among them, carbon dioxide transcritical refrigeration technology is more environmentally friendly than traditional technologies, and its energy efficiency is improved by more than 20%. this technology is applied to the beijing winter olympics speed skating hall. the temperature difference of the ice surface is controlled at 0.5℃, which is lower than the 1.5℃ standard proposed by the winter olympics organizing committee. the ice surface is flat, smooth, and the temperature conduction is uniform, making it the world's first winter olympics speed skating venue to use carbon dioxide transcritical direct evaporative refrigeration.
with the development of digital technology, data is increasingly becoming one of the core driving forces of modern technology. the exhibition area has set up a variety of functions of the green data center, such as the data center green technology system architecture diagram composed of ten advanced technologies such as immersion liquid cooling, intelligent micro-modules, digital management and control, and integrated power modules. it is reported that this technology system can effectively support the rapid development of greening in the current data center field.
in addition, an intelligent micro-module system was also demonstrated on site. the system has the advantages of integrated integration, rapid deployment, space saving, energy saving, and an average annual pue of 1.11. the fully immersion phase change liquid cooling server is suitable for high-power density data centers and has efficient heat exchange capabilities. the pue can be as low as 1.04 and can bring a new visual experience.
the exhibition area also showcased a variety of new technology products, such as a super liquid-cooled charging pile, which has a maximum output power of 600kw and a maximum output current of 600a for a new energy car with a standard range of 70kwh, and can charge 90% of the car in 10 minutes, bringing users an ultimate charging experience of "about one kilometer per second", which is similar to refueling. it is reported that the charging pile uses liquid cooling to dissipate heat, which can increase the life of the charging pile by more than 5 years. it is equipped with a high-definition touch screen, which can bring a good user experience. at the same time, the charging pile occupies a small space, with the main unit occupying less than 2 square meters and the liquid-cooled extension occupying less than 0.5 square meters; it has high stability and the equipment online rate exceeds 99%; the charging process is simple, supporting nfc card swiping or public account, mini program, app scan code charging, etc., and can use the functions of automatic identification of the plug-in, automatic scheduled charging and ultra-high power output to shorten the charging time of a single vehicle and improve the overall charging experience.
personal carbon ledger, one-click access to personal low-carbon emission reduction data
a machine called "beijing green living platform" has attracted many citizens to interact. by scanning the qr code on the touch screen with a mobile phone, you can create a personal carbon account book, and automatically record the carbon reduction from green transportation, green catering, garbage classification and other practices of green and low-carbon life in the personal carbon account book, and obtain corresponding green points incentives. you can also use the points consumption channels to exchange for cycling cards, coupons, vouchers, etc. provided by various platforms, using visible and tangible incentives to guide citizens to practice green and low-carbon life.
it is reported that in the three years since the beijing energy conservation and environmental protection center of the beijing development and reform commission launched the innovative "beijing green living season", it has established "personal carbon ledgers" for 6.7 million citizens through the "beijing green living platform", and has encouraged more than 400 million citizens to practice carbon reduction behaviors, effectively promoting the green transformation of citizens' lifestyles.
