The "Going green bubble"17 Mar 2020 12:45
Adrianz, I have read and respect your posts and credit you with a certain amount of intelligence, however the general public are starting to realise the devastation "Going green" is causing, Im not on about recycling (Which everyone should have doing for years) Im on about electric transport, have you actually goggled "Open cast Cobalt mine" look at the thousand of acres of prime jungle and rain forest and many many thousands of miles of prime river totally destroyed by Cobalt run off, why? to produce Lithium for car batteries, that's some thing Greta doesn't tell you, then where does the electric come from to charge your car? The Raw fuel-Power generation-Final usage is incredibly inefficient here are some facts ...The Energy Supply Chain
Much of the energy content of the available energy sources is wasted by inefficiencies the energy conversion and distribution processes. Considering domestic electric lighting as a typical example, less than 1% of the energy consumed to provide the electricity is ultimately converted into light energy. The other 99% is wasted in the supply chain. Using conventional fossil fuelled generating plant, losses accumulate as follows:
##10% of the energy content of the fuel is lost in combustion and only 90% of the calorific content is transferred to the steam.
##The steam turbine efficiency in converting the energy content of the steam into mechanical energy is limited to about 40%. (Carnot's Efficiency Law)
##The rotary electrical generator is very efficient by comparison.The conversion efficiency of a large machine can be as high as 98% or 99%.
##Transmission of the electrical energy over the distribution grid between the power station and the consumer results in a distribution loss of 10% mainly due to the resistance of the electrical cables.
##Further energy is lost due to the energy conversion efficiency of the end user's appliance. Incandescent lighting is particularly inefficient converting only 2% of the electrical energy into light
Some of the most inefficient ways to supply power stations are as follows
Biomass 35%
Wind turbine 35%
Municipal waste 25%
Solar Thermal 20%
Solar PV 15%
Geothermal 15%
All facts DYOR .............. Buy an electric car and kill the world quicker
