Very, very little. I don't suppose you have a link to a source that says otherwise?
“It is like using corn for fuel....It takes more energy to produce the so called green energy”
Not if you consider natural gas, nuclear, and hydro to be green.
You are delusional.....You apparently don’t read anything that comes close to science or engineering.
And no I won’t give you links....do your own research for a change. For years there have been articles detailing the energy costs of using methanol based fuels. When one does energy calculations you have to include all the energy values not just ‘the plug’
