We know how to make clean energy cheap. We've done it several times: wind, solar, LEDs, lithium-ion batteries. This decade, with proactive investment, governments and private sector innovators can finish the job and complete a toolkit for a prosperous net-zero emissions economy.
Our to do list:
-Advanced geothermal & nuclear, H2 combustion turbines, long-duration energy storage, cheaper HVDC transm.
-Hydrogen from electrolysis, gas reforming w/CCS & biomass gasification w/CCS
-Synthetic fuels
-CCS for cement
-Direct reduction of iron
-Direct air capture
None of these are radical breakthrough techs that need to come from scientific labs. These are all techs that have been demonstrated at pilot or commercial scale. We know how they work. Now we need to make them cheap, low-risk, scalable, just as we did for wind, solar, batteries
That will require combo of ongoing public and private RD&D, and most importantly, incentives and investment to deploy these technologies at scale, repeatedly, over the next decade, to drive experience, incremental innovation, learning by doing, and eliminate tech & execution risk
We know the play book. We've used it to score before. Now time to finish the game.
ps, keep investing in radical breakthrough techs in scientific labs too! the world doesn't end in 2050 (I hope!) or when we reach net-zero. We can keep the long game going too.

So let's talk about Budget Reconciliation, that 'one weird trick' the Senate majority uses to bypass the filibuster on measures related to revenue, spending and taxes. An explainer: budget.house.gov/publications/f…
Republicans used reconciliation in 2017 to pass the Trump/McConnell tax cuts that almost entirely benefited the wealthy & corporations, added $1.9T to the deficit, and killed the penalty for not getting health care. (They did pretty much the same thing in 2001, 2003, & 2006 btw).
Democrats can now use reconciliation to: expand unemployment insurance & $2,000 checks & $ for small biz to help Americans weather the pandemic, $ for vaccinations, rebuild our infrastructure, invest in US manufacturing, build clean energy, and tax the uber wealth. Seems fair.
Fabulous news! The MA Legislature passed the #Climate Roadmap Act, which updates the 2008 Global Warming Solutions Act and provides statutory requirement to reduce GHG emissions to net-zero by 2050, in line w/@MassGovernor's 2050 Roadmap released last week
In Oct 2019, I helped organize a letter from 37 scholars & experts "to confirm that the scientific underpinning for [the 2050 Roadmap Bill] is sound, technologies exist to put us on a path to achieving the goals, and there are viable policy pathways for achieving the targets."
My work on electricity decarbonization has demonstrated the importance of what I call "firm" low-carbon electricity generation technologies to enabling an affordable and reliable 100% carbon-free electricity system. See doi.org/10.1016/j.joul… & seminar
This work demonstrates that, under certain conditions, natural gas power plants w/CCS or burning hydrogen (possibly derived from methane reforming w/CCS) *could* play a firm low-carbon role in this 100% carbon-free electricity mix. THIS HAS NOTHING TO DO WITH GAS APPLIANCES.
They're right (with a few exceptions). Here's why...
We already have over 540 gigawatts of natural-gas fired generating capacity in the U.S. today. That's enough to meet about 2/3 of our nationwide peak in electricity demand. That's plenty of capacity to help manage the variability of weather-dependent wind & solar as they scale up
Those existing natural gas power plants will play a key role in the near-term as what I've termed "firm" generating capacity: available on demand (dispatchable), any time of the year, for as long as needed. (For more on firm generation, see doi.org/10.1016/j.joul…)
Here's 39 things President-Elect Biden could do to take #ClimateAction, featuring a round-up of voices from across the climate policy landscape: bloomberg.com/features/2020-…
My entry w/@CostaSamaras: appoint climate-focused Budget Director and White House Chief of Staff. Why? 🧵⤵️
President-elect Biden’s chief of staff and OMB director must align all federal agencies, spending, and legislative strategy around four big goals: ending the pandemic, rebuilding the economy, dismantling systemic racism, and confronting climate change. 1/
Cabinet secretaries get a higher profile, but no other positions beyond the President him or herself has a broader reach across the federal government than the Director of the Office of Management and Budget (OMB) and White House Chief of Staff. 2/
Wind, solar & battery costs have plummeted & energy storage installs are booming. Good timing for my new paper w/@dhariksm & @nsepulvedam on "Long-run system value of battery energy storage in future grids with increasing wind and solar generation"
Our new study out in @ElsevierEnergy's journal Applied Energy finds that the economic value of storage increases as variable renewable energy generation supplies an increasing share of electricity supply but that storage cost declines are needed to realize full potential.
We used a detailed electricity system planning model (energy.mit.edu/wp-content/upl…) to examine battery storage & determine key drivers that impact its economic value, how value changes w/increasing deployment over time, and implications for the long-term cost-effectiveness of storage.
