The true cost of wind energy is higher than most cost estimates calculate. Mandates requiring the use of wind energy increase electricity costs for consumers and subsidies mask the actual cost: file:///F:/Thorium/New%20Energy/True-Cost-of-Wind1.pdf
Modern solar panels are about 20% efficient. This just means that 20% of the energy in solar radiation is converted into electricity, while the rest is lost as heat. Even though this is actually quite decent, we would nevertheless need to completely cover an area the size of Spain in solar panels to generate enough electricity to meet global energy demands by 2030.
- 20 grams of silver per square meter of Solar panel
- 1 million panels Squared kilometer, this means 11.1 million grams, or 11.1 tons, of silver per square kilometer
- Spain is 506,000 square kilometers in area—This means that 5,616,600 tons of silver - Seven times the silver in the Earth's crust. https://www.nationaleconomicseditorial.com/2017/06/05/solar-powered-future-impossible/
Renewable Energy Policy distorts true cost of energy
“That is to say, the SREC costs 6X the kWh of energy costs. Making claims that PV solar costs 5 cents/kWh is misleading if the utility is paying 35 cents for it. Of course the utility buying the energy and the utility buying the SREC may be different. Because this is a lucrative opportunity, the article mentions that there is an increasing supply of SRECs. This should lower the price paid at auction. To prevent this, Massachusetts (for one) has set a floor price of $300/SREC. This creates an oversupply and the situation gets really complex, allowing SRECs to be applied to future years. Does anybody remember Enron?” Robert Hargraves
Solar manufacturing is mostly located in China, and the panels are often installed in Europe or the United States. At double the carbon intensity, it takes twice as long to compensate for the greenhouse-gas emissions as it does to pay back the energy investments.
“Does anyone believe that it is moral or wise to invest 10.5 Billion Tons of materials in contrast to 600 million Tons? That's 5.6% of the required materials for solar... 9% for wind... and 17% for Geothermal. It also takes energy to mine, refine and process these materials. Manufacturing, transportation, installment and upkeep also require energy and create emissions.” Mathijs Becker
