This argument is one massive false assumption. Renewable energy sources are becoming cheaper and are already cheaper than coal and nuclear. Cheap means they will become pervasive and replace the majority of existing sources. There is technically no reason we couldn't do it [3], rather "the key roadblocks are: climate change denial, the fossil fuels lobby, political inaction, unsustainable energy consumption, outdated energy infrastructure, and financial constraints".
It's only a question of time until renewables will kill fossil fuels. If only we'd stop subsidising fossil fuels [2].
The report you're quoting is itself highly questionable. Just as an example, wind speed averages are based on Cambridge, which isn't anywhere near the coast where wind turbines should live. Anything from a comprehensive report. Furthermore, he compares the energy to a random amount of energy (50% of energy consumed by cars). The report itself seems a little bit of warm air.
