Yintoni Imithombo Yombane Ejongene Nobomi Bakho?

Amandla kagesi aveliswa njani

Ngaba wakha wazibuza ukuba idivayisi yakho yeselula kunye nezinye iifowuni zihlawulwe njani? Ngaphandle kokusigcina sidibanise ne-digitally, umbane uphinde ulondoloze ubomi kwizibhedlele, kumashishini kunye nokugcina uqoqosho lwe-US oluya. Kungakhathaliseki ukuba ngumthombo wamandla we-19th Century njengamalahle okanye i-21 Century umthombo onjengelanga, kuyafaneleka ukuba ukwazi ukusebenza kwamandla kagesi, ukuba yenziwe njani kwaye apho iJusi esinika amandla ethu ubomi.

Oko Kufuneka Ukwazi NgoMbane wamandla

Amandla kagesi akhiwa ukuhamba kwee-electrons, ezibizwa ngokuthi "zangoku," ngokuqhuba umqhubi, njengefowuni. Umlinganiselo wamandla kagesi owenziwe kuxhomekeke kwinani lee-elektroni ezijikelezayo kunye nejubane lokuhamba. Amandla anokuba yinto enokwenzeka okanye ikinetic. Umquba wamalahle, umzekelo, umele amandla anokuba yikinetic xa itshisiwe.

Iifom eziqhelekileyo zamandla

Nazi iindlela ezithandathu eziqhelekileyo zamandla.

1. Amandla ekhemikhali. Oku kugcinwe, okanye "amandla," amandla. Ukukhulula amandla ekhemikhali kwii-fuel-based based fuel fuels requires fuel as the burning of charter, oil, gas, or biomass like wood.
2. Amandla ashushu. Imithombo yendalo yamandla ashushu iquka ukushisa okuvela emithonjeni yamanzi eshushu, ukushisa kwamafutha kunye ne-biomass (njengoko kuchaziwe ngasentla) okanye iinkqubo zoshishino.
3. Amandla oKinetic. Amandla e-Kinetic ahamba, ayenzeka xa amanzi ehamba ngamanqatha okanye ahamba emanzini, okanye xa umoya uhambisa ama-wind turbine emoyeni.

1. Amandla enyukliya . Le ngamandla agcinwe kwiibhondi ngaphakathi kwee-atom kunye nama-molecule. Xa amandla enyukliya akhululwa, angakhupha i-radioactivity kunye nokushisa (amandla ashushu).
2. Amandla esola . Amandla aphuma kwilanga kunye nemibala yokukhanya ingafakwa kunye ne-photovoltaics kunye ne-semiconductors. Izibuko zingasetyenziselwa ukugxininisa amandla. Ukushisa kwelanga kunomthombo oshushu.

1. Amandla okujikeleza. Le ngamandla avela ekutheni, eveliswa ngamacebo okucwangcisa njengama-flywheels.

Indlela Amandla Amandla athelekisa ngayo

Kukho intetho eninzi malunga nemithombo yamandla emihle kunye embi nendlela (okanye ukuba) inxaxheba kwiinguqulelo zemozulu. Ngaphambi kokuba ube yingxenye yencoko, nantsi indlela ekujonga ngayo imithombo yamandla e-US ngokweSikhungo soPhando loMbane (IER).

• Amafutha asefresil 67% ( amalahle angama-41%), ioli (5.1%), igesi yendalo (21%)
• Amandla ahlaziyiweyo 16% (ikakhulukazi ama-hydroelectric (92%), umoya (6%), i-geothermal (1%), kunye nelanga (1%)
• Amandla enyukliya 13%
• Eminye imithombo 3% (okt, i-biofuels kunye ne-biomass)

Yiyiphi Ixesha Elizayo

Xa iBhunga loKhuselo loLondolozo lweNdalo lusekwe kwiminyaka yee-1970 ukukhusela imo, ukufudumala kwehlabathi kwakungekho kwi-radar yomntu. Namhlanje, awukwazi ukusinda umcimbi. Ngokutsho kwe-IER, phakathi kuka-2013 no-2040, ukusetyenziswa kwegesi yendalo kulindeleke ukuba kwande ngo-13.4% kunye nokusetyenziswa kwamalahle ngama-5.6%. U-IER ubona i-fuel fossil egcina isimo sayo njengeMelika ehamba phambili yokusetyenziswa kwamandla ubuncinane ukuya kube ngu-2040, ukubonelela nge-80% yezidingo zamandla esizwe.
