ʻO nā mea hoʻololi wela he mea hoʻopakele ikehu e ʻike ai i ka hoʻoili wela ma waena o ʻelua a ʻoi aku ka wai i nā wela like ʻole. Hoʻololi ia i ka wela mai kahi wai wela kiʻekiʻe i kahi wai wela haʻahaʻa, i hiki ai ka mahana o ka wai i ka ʻōnaehana kaʻina, nā mea hōʻailona i ʻōlelo ʻia e hoʻokō i nā pono o nā kūlana kaʻina, i ka manawa like, ʻo ia kekahi o nā mea hana nui e hoʻomaikaʻi ai. ikehu pono. ʻO ka ʻoihana hoʻololi wela e pili ana i nā ʻoihana 30, e like me ka HVAC, ka mālama ʻana i ke kaiapuni, ka hana pepa, ka meaʻai, ka ʻoihana kemika, metallurgy, ka mālama ʻana i ka ea, ka mālama wai etc.

Hōʻike ka ʻikepili i ka nui o ka mākeke o ka ʻoihana hoʻololi wela o Kina i ka makahiki 2014 ma kahi o CNY66 biliona, ʻoi loa ma ka ʻoihana o ka aila, ʻoihana kemika, metallurgy, mana uila, kūkulu moku, hoʻomehana waena, refrigeration a me ka ea ea, mīkini, meaʻai, a me nā lāʻau lapaʻau. etc. I waena o lākou, ʻo ka ʻoihana petrochemical ka mākeke nui loa no ka ʻoihana hoʻololi wela, me ka nui o ka mākeke ʻo CNY20 biliona, ʻo ka nui o ka mākeke hoʻololi wela i ka pā mana metallurgy ma kahi o CNY10 biliona, ʻo ka nui o ka mākeke hoʻololi moku. ʻoi aku ma mua o CNY7 biliona, ʻoi aku ka nui o ka mākeke o nā mea hoʻololi wela i ka ʻoihana mechanical ma kahi o CNY6 biliona, ʻoi aku ka nui o ka mākeke o nā mea hoʻololi wela i ka ʻoihana hoʻomehana waena ma mua o CNY4 biliona, a ʻo ka ʻoihana meaʻai pū kekahi ma kahi o CNY4 biliona. Eia kekahi, ʻo nā kaʻa aerospace, nā mea semiconductor, ka mana nuklea, nā turbines makani, ka mana photovoltaic solar, ka ikehu a me nā māla ʻē aʻe e koi i ka nui o nā mea hoʻololi wela ʻoihana, a ʻo kēia mau mākeke ma kahi o CNY15 biliona.

ʻO ka ʻoihana meahana hoʻololi wela i hana i nā mea kupaianaha i ka noiʻi ʻana i ka mālama ʻana i ka ikehu a me ka mālama ʻana i ka kaiapuni, ka hoʻomaikaʻi ʻana i ka maikaʻi o ka hoʻololi ʻana i ka wela, ka hōʻemi ʻana i ke kaomi, mālama i nā kumukūʻai, a me ka hoʻomaikaʻi ʻana i ka ikaika wela o nā mea hana a me nā mea ʻē aʻe. ʻO ka manawa, e mālama ka ʻoihana hoʻololi wela o Kina i ka awelika o ka ulu ʻana o ka makahiki ma kahi o 10% mai 2015 a 2025.
