I think so long as fossil fuels are cheap, people will use them and it will postpone a movement towards new technologies.

In this quote, Paul Krugman highlights the relationship between the cost of fossil fuels and the pace of transition to renewable energy technologies. He argues that as long as fossil fuels remain cheap, there will be little incentive for individuals, businesses, or governments to invest in cleaner and more sustainable energy solutions. The low cost of fossil fuels creates a barrier to the adoption of new technologies because they often require initial investments that may not be immediately attractive in comparison to the convenience of cheap, readily available fossil energy.

Krugman’s statement suggests that the economic reality of cheap fossil fuels can postpone the shift toward more sustainable forms of energy. When fossil fuels are inexpensive, there is less urgency to develop and implement alternative energy sources like solar, wind, or hydroelectric power. This reflects the classic issue of incentive—without the right economic drivers, people and organizations are unlikely to make the transition, even if they know it is necessary for the future of the planet.

The quote also speaks to the economic inertia of energy markets. Even when there is growing awareness of the environmental damage caused by fossil fuels, the financial and practical realities of using them keep many from pursuing more eco-friendly options. This highlights the need for policy interventions, such as carbon taxes, subsidies for renewable energy, or regulations that make fossil fuels less attractive economically, in order to create a market incentive for change.

Ultimately, Krugman’s quote serves as a reminder that while the technology for cleaner energy may exist, the economic landscape must shift in order for those technologies to be implemented on a wide scale. Rising fossil fuel costs or government action may be necessary to accelerate the adoption of sustainable energy solutions, but until that happens, the cheapness of fossil fuels will continue to be a powerful force slowing the transition.
