Recent history suggests that researchers and businesses can deliver the necessary advances and cost reductions (see sidebar, “Charting cost reductions for climate technologies”). 122–34, Arvydas Lebedys et al., Renewable energy statistics 2021, International Renewable Energy Agency, March 2021,. Albardi, Simona Bigerna, and Carlo Andrea Bollino, “Estimating the learning curve of solar PV balance–of–system for over 20 countries: Implications and policy recommendations,” Journal of Cleaner Production, September 20, 2018, Volume 196, pp. Trancik, “Evaluating the causes of cost reduction in photovoltaic modules,” Energy Policy, December 2018, Volume 123, pp. ![]() ![]() Goksin Kavlak, James McNerney, and Jessika E. Roughly $255 billion of solar modules were sold over this time frame, with economies of scale and “learning by doing” in manufacturing accounting for the majority of cost reductions. Then, from 2000 to 2014, governments offered incentives, via mechanisms such as feed-in tariffs and renewable portfolio standards, that encouraged utilities and other organizations to buy and install solar systems. During the first phase, between 19, R&D investments accounted for the majority of cost reductions, and deployments of solar modules were relatively small (about $15 billion). Analysis suggests that the cost reductions occurred in two phases, each of which saw cost declines of about 85 percent in the cost of solar modules. after more than 30 years of research and investment, during which solar-module costs fell by about 98 percent and about $270 million worth of panels were deployed. Levelized cost of energy, levelized cost of storage, and levelized cost of hydrogen, Lazard, October 19, 2020,.

Integrating most climate technologies into existing infrastructure, hardware, software, and operational systems will be complicated, too. Uncertainty about the availability of financing for innovation limits capital formation and slows scale-up. Similarly, unless manufacturers of utility-scale batteries can make them at low cost, power producers will have to keep running fossil fleets to cope with the intermittency of renewables. When, for example, will clean hydrogen cost $1 per kilogram: in 2025 or 2050? The answer will affect the speed at which industries from aviation to steel can decarbonize. This need for innovation makes the pace of decarbonization difficult to predict. ![]() The challenge is that further abatement must come from climate technologies that aren’t quite ready, including 25 to 30 percent from technologies that are demonstrated but not yet mature and another 10 to 15 percent from those still in R&D. The good news: McKinsey research on Europe’s net-zero pathway suggests that climate technologies that are already mature could, if deployed widely, deliver about 60 percent of the emissions abatement that will be needed to stabilize the climate by 2050. New technologies represent a critical part of the world’s decarbonization tool kit-and the world does not yet have all the technologies that it would need to solve the net-zero equation by balancing sources and sinks of greenhouse-gas (GHG) emissions.
