Clean energy – mainly solar, geothermal, hydro, wind, and unconventional biofuels – is perfectly capable of powering our economy. It can be made reliable, large-scale, and cost-effective. But that’s true only if we commit to build clean energy infrastructure on a scale comparable to the fossil-fuel apparatus built over the past century. That scale is enormous.
The U.S. Energy Information Agency estimates we need to invest more than $45 trillion in our energy infrastructure over the next 40 years to meet future demand. That’s the kind of money we invest in fossil fuels. It’s only fair then to ask how clean energy might perform with similar levels of capital. What do you get for a trillion dollars?
That’s just the question I’ll ask in a series of 10 articles on The Mark about clean energy over the coming weeks. The answers may surprise you. Some clean technologies scale up, bringing costs down. Others hit supply constraints and can’t substantially displace fossil fuels. But make no mistake – clean energy performs if given a fair shake.
At that scale of investment, giant solar plants produce energy well after the sun goes down, at a lower cost than melting tar. Unconventional bio-fuels grown in the desert replace half the world’s oil supply. By drilling for heat instead of oil, we use enhanced geothermal energy to replace North America’s entire coal infrastructure. Our aging grid is replaced by a new continent-wide energy internet, which connects multiple, distributed energy sources.
