“Wind turbine’s real production is less than half of what it is alleged to be.” – Anon
Renewables are a dead loss, economically, in reliability, and ecologically. Anonymous Contributor
You’ve swallowed the green propaganda on renewables hook, line and sinker. Wind and solar are wasters of resources. They are net energy SINKS when all of their actual energy inputs are taken into account.
For instance wind turbines frequently draw power FROM the grid to maintain themselves. They cannibalise the grid and have nothing to contribute to the future of humanity. Renewables salesmen exaggerate the lifespan of wind and solar generators to about twice their real productive life, especially for wind. Wind turbines are typically given a theoretical lifespan of 30 years. In practice they are uneconomic to run (even with their massive subsidies) at 15 years of age on land, and 12 years in the case of offshore wind turbines. This means that their real costs are actually more than twice their alleged costs, or put another way, their real production is less than half of what it is alleged to be.
Solar panels lose on average 2% efficiency each year due to the effects of UV on the solar cells and physical external degradation caused by their local environment. In dusty areas, knock off another 25% efficiency (recorded in China and India). In humid tropical/sub-tropical areas, knock off up to 75% efficiency if they are not constantly cleaned (moss and algal growth quickly covers the glass panels). In the hotter, sunnier parts of Australia they are failing at 10 years of age, not the 25 years that all of their production calculations are based on. Even operating at their best, solar panels are a very inefficient, lousy way of capturing a very diffuse source of energy. Coal and gas are concentrated energy sources.
