Zakaj so solarne elektrarne prava stvar

V analizi, ki uporablja podatke do leta 2010, pač ni vsebovan nenačrtovan padec cen v 2010-2012.

Ne tega ni težko razumeti, problem je v tem, da je to NAPOVED za 2017 in je bila narejena leta 2012...
Še enkrat, mislim da sem ti tole zadevo v nos vrgel že vsaj 5x, pa še vedno iščeš neke astralne razloge, da ni relevantna, he he, saj ne rečem, si prav luškan, pa dajmo še šestič (saj to veš kaj .gov v domeni pomeni, ne? Pa take zadeve kot "National Energy Modeling System"? Težko boš navedel vir za fotovoltaiko, ki ima tako težo... :D):


Estimated Levelized Cost of New Generation Resources, 2017
http://www.eia.gov/forecasts/aeo/pdf/03...

Photovoltaic capacity estimates for recent historical years (2009 and 2010) were updated to line up more closely with Solar Energy Industries Association (SEIA) and Interstate Renewable Energy Council (IREC) reports.

Data in the electricity model were revised to reflect 2009 electric utility financial data (electric utility plant in service, operations and maintenance costs, etc.) and refine the breakdown of associated costs between the generation, transmission, and distribution components.

Sploh pa so to cene za ameriške elektrarne. V Sloveniji so cene znane: TEŠ6 bo s 100€/MWh komaj prišel na nulo, sončne elektrarne pa z 98€/MWh delajo dobiček. Tebi pa je to očitno silno težko razumeti.

TEŠ bo s 100€/MWh prispeval 60€ v blagajno za sončne elektarne, medtem ko sončne elektrarne ne bodo prispevale niti tolarja.

Pravtako hočem svojih 120€ nazaj.

Problem je v tehnologiji, premogovništvo bo pač treba opustiti, ker je eden od najslabših in najbolj zgrešenih virov energije.

Zamenjave za termoelektrarne obstajajo (sončne in vetrne elektrarne) in se tudi vedno bolj širijo po svetu. Glavna ovira za prenehanje s premogovništvom je predvsem inercija premogovniških lobijev in neinformiranost in zastarele predstave ljudi o dejanskem stanju.

V Španiji na višini 50m ni povprečje 5m/s, ampak manj:

V Sloveniji je na višini 80m tudi višje povprečje kot na 50m.

Skratka: v Sloveniji imaš kup lokacij, kamor lahko postaviš vetrne elektrarne.

Ampak še vedno imaš v Sloveniji cel kup enakih lokacij.

The more a country depends on such sources of energy, the more there will arise – as Germany is discovering – two massive technical problems. One is that it becomes incredibly difficult to maintain a consistent supply of power to the grid, when that wildly fluctuating renewable output has to be balanced by input from conventional power stations. The other is that, to keep that back-up constantly available can require fossil-fuel power plants to run much of the time very inefficiently and expensively (incidentally chucking out so much more “carbon” than normal that it negates any supposed CO2 savings from the wind).

Both these problems have come home to roost in Germany in a big way, because it has gone more aggressively down the renewables route than any other country in the world. Having poured hundreds of billions of euros in subsidies into wind and solar power, making its electricity bills almost the highest in Europe, the picture that Germany presents is, on paper, almost everything the most rabid greenie could want. Last year, its wind turbines already had 29GW of capacity, equivalent to a quarter of Germany's average electricity demand. But because these turbines are even less efficient than our own, their actual output averaged only 5GW, and most of the rest had to come from grown-up power stations, ready to supply up to 29GW at any time and then switch off as the wind picked up again.

Mater kolk ti nič ne bereš.

Poleg tega pa ti vetrnice sredi njiv ne bodo prav nič koristile.

Vetrne ki jih realno nimaš kam postavit

dva posta za tabo je jest10 napisal, da je TEŠ6 krvavo potreben. Podobno je nekje proti začetku teme napisal SplitCookie. Tako da tudi tukaj nekateri očitno podpirajo take projekte.

Ja saj je ni. Al maš TEŠ al NEK ali se pa jebi in zmrzuj sredi zime.
Druge opcije nimaš

Aja, imaš. 200€/MWh

In glede veternic: Res dobra študija, ki še vedno upošteva samo 30% izkoriščenost

TEŠ6 bi s tistimi 500MW letno oddal ... 4TWh

Ja in? To je realna ocena in to je treba upoštevati.

Valim se po tleh od smeha
Realno je 10%, ozeroma še to ne. Nemci imajo 16%
