Geen mirakel nodig voor 100% hernieuwbare energie in 145 landen
Recente studie...
Kostenplaatje $ 62 billioen dollar (onze billioen ;-), in US = triljoenen)
Maar dat geld is in minder dan 6 jaren terugbetaald omdat vervuilende energie die landen $ 11 biljoen per jaar kost.

No miracle tech needed: How to switch to renewables now and lower costs doing it
BY MARK Z. JACOBSON, OPINION CONTRIBUTOR - 06/28/22
...
We found that the overall upfront cost to replace all energy in the 145 countries, which emit 99.7 percent of world carbon dioxide, is about $62 trillion. However, due to the $11 trillion annual energy cost savings, the payback time for the new system is less than six years.
The new system may also create over 28 million more long-term, full-time jobs than lost worldwide and require only about 0.53 percent of the world’s land for new energy, with most of this area being empty space between wind turbines on land that can be used for multiple purposes. Thus, we found that the new system may require less energy, cost less and creates more jobs than the current system.
Another interesting finding was that, with a fully renewable system, charging battery-electric vehicles during the day was less expensive for the grid than charging them at night because day charging matched well with solar electricity production.
According to Anna von Krauland, a Stanford Ph.D. student who participated in the study, a main implication is that it “tells us that for the 145 countries examined, energy security is within reach, and more importantly, how to obtain it.”

Zal ook wel in de gazetten staan... of niet?
Die 145 landen zijn verantwoordelijk voor 99,7% van "de wereldwijde uitstoot van CO2 door energie" |
