Noen innfall og stjålne innlegg for å hjelpe meg å huske hvor håpløs miljøkampen egentlig er.
Could humans maintain an ecosystem on the Moon or Mars? In 1991, 8 researchers locked themselves inside this 3.14-acre sealed structure in the Arizona desert for 2 years to test just that. It remains the largest and longest experiment of its kind, ever.Biosphere 2 was built to be an isolated, self-sufficient ecosystem, modelled after the … Les mer
Alexander Stahel My view: unless the West get its decarbonisation targets & deadlines in line with China (& India), reducing CO2 is 100% risk and 0% reward. What drives policy? In short: @IPCC_CH. Scientists there believe an increase of 1.5C is the “safe limit” for global warming while higher temperatures may change the environment and, … Les mer
Energikommisjonen la fram rapporten sin i februar 2023. Den handler ikke om konkrete prosjekter, men beskriver 40TWh ekstra som realistisk i løpet av de neste sju årene. La meg forsøke å tegne et bilde av hva det er: Statnett sier: Motstanden mot vindkraftutbygging på land og begrenset potensial for vann- og solkraft, gjør at havvind … Les mer
A contradition in terms? Forbruk i 2022: 7,9 million barrels/day = 1,25 mrd liter/dag = 458 mrd liter/år = 365 mill tonn/år. An estimated 1 billion dry tons of biomass can be collected sustainably each year in the United States, enough to produce 50–60 billion gallons of low-carbon biofuels (= 210 mrd liter/år). 1 tonn jet fuel … Les mer
IEAs Net Zero Emissions scenario anslår at batterikapasiteten vil øke fra 27 (+9 siste år) GW i 2021 til 780 GW i 2030 og 3500 GW i 2050. Flow battery Flow batteries could emerge as a breakthrough technology for stationary storage as they do not show performance degradation for 25-30 years and are capable of … Les mer
As a miner for 40 years I have worked in various mines around the world. Gold, platinum, copper, coal, lead, zinc, oil and salt. I’m going to tell you something, and here it is. We will destroy the earth in the name of «Green Energy» Follow along and I will explain. MiningWatch Canada is estimating … Les mer
Vi trenger 4,5 milliarder tonn kobber, seks ganger alt kobber vi hittil har gravd ut. Det er også fem ganger mer enn de kjente reservene og med dagens kapasitet for kobberutvinning vil det ta 190 år. Dette tar ikke inn at man også må utvide overføringsnettet. Det er kun snakk om kraftkildene, og det er … Les mer
A plant will use 20 megawatts to produce 8000 tons of transportation fuel per year, This method will avoid producing 28,600 tons of CO2 annually from fossil fuels. 20 MW 24/365 is equivelant to 175 GWh/year. That could power electric cars for 1000 million kilometers or produce enough diesel to power fossile fuel cars 167 … Les mer
The energy transition has no plan – just goals Doug Houseman (Principal Consultant at Burns & McDonnell) about energy storage. Doug is a leader and visionary in grid and utility modernization.
What do we need? According to the International Renewable Energy Agency (Irena), the world will need 19 exajoules of green hydrogen in the energy system in 2050 — between 133.8 million and 158.3 million tonnes a year. Recharge calculations show that producing such a volume would require at least 6,690TWh of dedicated electricity every year … Les mer
