The biggest issue that so many people underestimate is how many jobs will be LOST by making fossil fuels obsolete. Im not saying i dont support renewables (I strongly believe in them!), but think there are tons of special interest groups (employees, unions, local governments, etc) who do not want to lose the jobs of miners, drillers, drivers, pipe fitters, chemical engineers, geologists, etc when fossil fuels are replaced. They will do whatever they can to discourage renewable energy... through obstructionist regulations and laws, smear campaigns, or artificially decreasing the cost of fossil fuels... even though its not sustainable.
The stone age didnt end due to a lack of stones. The oil age wont end due to a lack of oil.
Yes! I totally agree. Btw, thank you for your comment! I understand their points but there's a planet to save. Not in 2050, right now, because climate change show their negatives effects and if we do nothing, we will loose our beautiful planet sooner than we think...
