Energy guru Daniel Yergin recently pointed out what he
sees as the four biggest challenges of a transition to green energy. These are:
1) maintaining energy security – as recent geopolitical
events have shown, we have a clear need to keep existing forms of fossil energy
(80% of global energy) in sufficient supply at reasonable cost. Avoiding price
shocks is important. Relying on suppliers like Russia and Iran is not smart nor
feasible. Reduced investment in fossil fuels has taken a toll on Europe and
other places and is now being increased. This also perhaps includes maintaining
grid reliability, which could be considered a kind of energy security. 2)
scaling up – change will happen slowly as scaling up is a major
challenge. Important considerations include the fact that heavy industry is
almost entirely reliant on existing fossil energy. These include what Vaclav
Smil calls the four essential pillars of modern civilization: steel, concrete,
plastics, and ammonia (for fertilizer). Those industries will take time in
decades decarbonize even partially. 3) developing countries
need the affordable energy access provided mostly by hydrocarbons to become
prosperous. They need modern reliable energy systems and cannot afford
to pursue renewables and deal with the variability and intermittency. 4)
the demand for metals and minerals. The supply of metals and
minerals must increase manyfold in order to supply what is needed for planned
increased deployments of solar and wind generation, EVs, and batteries. This
will not be easy, cheap, environmentally benign, nor well received by people
living near mines and some governments. Chile just rejected a huge copper and
iron mine project. Columbia just called for no new oil and gas exploration in
the country. Solar, wind, and electric transmission projects are facing
numerous public opposition hurdles. Demand for these minerals and metals is
likely to lead to more price spikes which will inflate project costs.
Each of these
challenges is daunting. Each will require huge expense, overcoming logistical
challenges, policy changes, and perhaps most important time. Simply throwing
money at these issues will not be enough. Thus, we need to consider that many
of these aspirational net-zero pledges and mandates will get further behind
schedule and ultimately not be met in the time frames imagined. There also
needs to be more pushback against those who unrealistically assert that we can
decarbonize fast and deep. It is just rhetoric. I would venture that to globally
decarbonize fully, maintaining reliability, by 2050 would take several hundred
trillion, perhaps even close to a quadrillion dollars.
