"Let's get real about alternative energy"...

is the title of this commentary piece by David MacKay, professor of physics at the University of Cambridge. Story highlights:
  • Replacing fossil fuels will take a massive level of construction
  • Most people don't understand the size and scope of the effort needed
  • Turning off cell phone charger is a minuscule contribution to saving energy
  • Hydrogen-powered cars use too much energy to solve the problem
