I think he means its easy from a technology standpoint. There are still a ton of politics at play here.
We know how to build solar, wind and nuclear plants, do that and just shut down coal power plants. That is like half. Then keep working to get old inefficient cars off the roads. Tax SUVs and give tax breaks to electric buyers.
None of these things are politically easy, but technologically require nothing new and might leave us with a stronger more economy because of the amount of new players and innovations in the fields affected.
But the current political discourse is functionally stalled on the issue because people don't care until it unambiguously affects them. That works great for many smaller issues but for this by the time it affects the average voter we are fucked.
This is a pretty naive view. There are no electric replacements for some of the big consumers of oil (trucking, shipping, airlines, construction equipment, etc).
There are already plans in various places to equip highways with overhead wires that will allow trucks to operate like trams for the duration.
Never mind that diesel engines, used in most heavy machinery, is not as picky about its fuel as a gasoline engine is. As long as it goes bang under pressure, a diesel engine can potentially run on it. what is not needed is to electrify anything, but that CO2 in vs CO2 out sums to zero (or a lot damn closer to it than it currently does).
Electrifying all of the highways and roads trucks drive on would basically be building an entire grid again. That doesn't really fall under the technically feasible category.
Interesting historial fact: the reason the USA was able to engage the Japanese relatively quick after Pearl Harbor is because the shit bunker fuel ships use doesn't burn easily at all so the ship fuel reserves were left intact.
There will be soon enough. And even if there was no way to match liquid hydrocarbon fuels for some applications then we just need to make those fuels from renewable sources.
Trucking can easily be electrified and the majority of transport related co2 including airplanes, trains, and cargo ships is from personal light road vehicles. Cargo ships are less than 2%, trains are less than 1%. Airplanes are around 7%. Around 30% is trucking. Construction vehicles are all electric/hydraulic already but more importantly are an insignificant source of co2.
Long distance semi tractors drive 500-800 miles a day. That doesnt require a huge battery.

You're joking right? Do you realize how much weight they tow compared to the weight of a Tesla? On top of that most of the Tesla weight is the battery itself.
Battery powered semis for long haul is absolutely not a solution.
Those wouldn't need electricity, however, if you decide to run them off of some kind of renewable bio-fuel or even just natural gas from renewable sources. The main thing is to switch them off of fossil fuels ASAP, then you can move from there to whatever future tech comes along later.
Reducing emissions is strictly a moral argument that has not been won. We don't have to cut CO2. But we should because it is the right thing to do. All the economic hocus pocus of the last couple of decades has not convinced people of that fact.
