Everyone knows that fossil fuels won't last forever. Something needs to change at some point, regardless of whether the issue is climate change or because we need a practical replacement for petroleum as cheap supplies run out. But while headlines suggest that a green-energy paradise is around the corner, not many are aware of the immense technical challenges that stand in its way. To turn our backs on fossil fuels, a staggering amount of work will be required to refit a global energy sector that has grown systematically for over a century. News of the latest green advancements can make it seem like plug-and-play technology, and simply a matter of switching from one source to another. In reality, the challenge is far greater, and infinitely more complicated. To make matters worse, environmentalists and fossil-fuel defenders wage continuous but fruitless war, and the growing gap makes it impossible to have any sort of constructive dialogue. Each camp becomes more locked in their position with every exchange, and the most revolutionary ideas never see the light of day. Instead of building, time and money are wasted sparring. Sparing no sacred cows, Terry Etam cuts through the media rhetoric, government propaganda, and widespread ignorance of the energy sector to get to the heart of what needs to change-and what needs to stay the same-if the challenges of moving away from fossil fuels are to be met, while maintaining the quality of life we have come to expect and rely on.
