(To try your hand at navigating the policy dilemmas, play our - admittedly simplified! - game below: “A president’s climate quandary.Hi Valued User, thanks for using the App! Their perspectives inevitably differ, and the lack of consensus - combined with very real efforts to exert pressure on the policymaking process - is a key reason that climate action is so politically difficult. Last year The New York Times asked, for instance, “whether any climate policy is both big enough to matter and popular enough to happen.” Durable climate policy requires securing buy-in from a range of actors, including politicians from both parties, business leaders, and civil society. These decisions are particularly difficult for politicians, who tend to focus on policies with immediate, local benefits that voters can see. Reducing humanity’s reliance on fossil fuels requires investments here and now that provide uncertain, long-term benefits. Minimizing the impact of climate change requires re-making a multi-trillion-dollar industry that lies at the center of the economy and people’s lives. However, in addition to the engineering challenges, the nature of climate change makes it politically challenging to deal with as well. Science clearly tells us that we need to remake our energy system and eliminate CO 2 emissions. But for aviation, maritime shipping, or long-haul trucking, where the vehicle must carry heavy loads for long distances without refueling, the difference in energy density between fossil fuels and batteries is a huge challenge, and electric vehicles just don’t meet the need. For vehicles that carry light loads and can refuel often, like passenger cars, this penalty isn’t a big deal. These advantages make up for some of the battery’s weight penalty, but an electric vehicle will still be heavier than a similar vehicle running on fossil fuel. On the other hand, electric motors are much more efficient than internal combustion engines and electric vehicles are simpler mechanically, with many fewer moving parts. Pound for pound, gasoline or diesel fuel contain about 40 times as much energy as a state-of-the-art battery. Electric vehicles are a much-touted solution for replacing oil, but they are not perfect for all uses. ![]() A vehicle needs to carry its fuel around as it travels, so the weight and volume of that fuel are key. The energy density of fossil fuels is particularly important in the transportation sector. Finally, fossil fuel generation often fills in the gaps in renewable generation today, especially natural gas generation, which can be efficiently ramped up and down to meet demand. Perhaps excess electricity can be used to create hydrogen or other fuels that can be stored and used at a later time. But longer-term storage poses a greater challenge. Storage solutions work well over a timeframe of hours - storing solar power to use in the evening, for example. Hydroelectric dams can serve this function now, and declining costs will make batteries more economic for power storage on the grid. Power storage technologies can save excess electricity to be used later. Demand-response strategies can encourage customers with flexibility in their processes to use more power when renewable power is available and to cut back when it isn’t. Power grids that cover a larger area are easier to balance, given that if it isn’t windy or sunny in one location, it may be somewhere else. Engineering challenges beget engineering solutions, and a number of solutions can help. ![]()
