The Ministry of Natural Resources and Environment (MONRE, Vietnamese: Bộ Tài nguyên và Môi trường) is a government ministry in Vietnam responsible for: land, water resources; mineral resources, geology; environment; hydrometeorology; climate change; surveying and mapping; management of the islands and the sea.
The main contributor to the country's emissions is fossil fuel combustion, which accounted for about 60% of greenhouse gas emissions in 2014. [3] As of 2018, the electricity sector accounted for 48% of Vietnam's CO 2 emissions from fossil fuel combustion, industry for 28%, transport 16%, the residential sector 4%, the commercial sector 3%, and agriculture 1%.

Most of southern Vietnam, including Ho Chi Minh City, endured the longest heat wave in 30 years. Farmers in the Mekong Delta faced decreased crop yields. [41] [42] In the province of Đồng Nai, mass fish deaths blanketed the entire view of a 300-hectare reservoir due to dwindling water levels caused by the heat wave. [43]
Vietnam had the fastest growth in coal use in Southeast Asia during 2011-2021, at an annual growth rate of 11%. [4]Data of the Ministry of Industry and Trade (MOIT), 10 months of 2018 coal production was estimated at 34.35 million tons, up 10% over the same period in 2017, of which clean coal output of Vinacomin (TKV) was 29.6 million tons, up 10.9% over the same period last year.

A heat pump CoP increases as the temperature difference, or "Lift", decreases between heat source and destination. The CoP can be maximized at design time by choosing a heating system requiring only a low final water temperature (e.g., underfloor heating), and by choosing a heat source with a high average temperature (e.g., the ground).
Hoàng is the head of IDG Ventures, a leading tech, retail and media angel fund in Vietnam. He is also the Chairman of the Vietnam Basketball Association, the owner of Saigon Heat and of McDonald's franchises in Vietnam. Nguyễn Minh Triết is an officer of the Ho Chi Minh Communist Youth Union.
In the 1930s metallurgists Albert Portevin and D. Seferian attempted to experimentally determine heat transfer characteristics in welding. [1] They correlated the effects of several factors—material properties, welding process, and part dimensions—on temperature distribution, by performing oxyacetylene (gas) and covered electrode (arc) welds on plates and bars of various profiles, and ...
Internal heat is the heat source from the interior of celestial objects, such as stars, brown dwarfs, planets, moons, dwarf planets, and (in the early history of the Solar System) even asteroids such as Vesta, resulting from contraction caused by gravity (the Kelvin–Helmholtz mechanism), nuclear fusion, tidal heating, core solidification (heat of fusion released as molten core material ...
