Technology

In case you're ever wondering, this is an example of your tax dollars at work. Thirty years ago solar and wind generation had to be heavily subsidized with government grants to make them viable in the energy market. Now the technology of both has advanced to the point that it's undercutting all of the other forms of electricity generation, without subsidization.

Government subsidies work. They're effective for getting new technologies off the ground.

It is now. But only after we invested in it.

This is a great example of investing in tech even when it’s not practical in the present day. It can pay off later down the line.

There have been studies (this one, for example) that suggest the total radioactivity-related health impacts from coal power exceed that of nuclear power by an order of magnitude. That's not all pollution-related deaths for coal -- just those associated with radon exposure inside of mines, and radioactive materials embedded in coal going out into the environment. For all the fear-mongering about nuclear, it's hard to find a less dangerous source of base load generation using present-day technologies. Maybe once grid-scale batteries are available at scale, they could replace nuke plants, but that's a solution ten years too late for an environmental problem we have to fix right now.

i wonder where the world we be today if we didnt stop funding nuclear, if gen 4 designs actually had proper money pushing them forward.

What is renewable about nuclear? It's not a fossil fuel, but uranium has to be mined and is a finite resource just like oil.

The infuriating thing to me is, renewable energy is often extremely independent. It means no reliance on foreign oil. That SHOULD be the most American thing, especially for those in the GOP who claim to be anti-government.

Goes to remind you their main product is hypocrisy.

No, the grid won't get greener if Trump is elected because he WILL go full dictator. And he will revert everything that is being done currently.

I don't think anyone is under the illusion that natural gas is emissions-free.

6% Solar + 6% Hydro + 10% Wind + 18% Nuclear = 40% "emissions-free"

The article doesn't do a good job of explaining the 40%, you have to infer it. But when you do, it isn't natural gas, but solar + wind + hydro + nuclear.

This is actually fantastic news. 40% renewable, 40% natural gas, and 20% coal is a huge step in the right direction.

I didn't mind the pie chart, the slices are labeled clearly, no need to use coloring like you have to read a legend.

Car manufacturing is, itself, a messy process. And we'd all be better off (for a whole host of reasons) if we could move to a public transit system and away from the messy, overly-complex, extraordinarily expensive highways-and-byways personal vehicle system.

Electrified rail and Multi-family homes would dramatically reduce both energy consumption AND housing costs, if we were willing to invest in it at rates comparable to what we spend subsidizing new fossil fuel wells, road expansion/maintenance, and policing of the homeless.

You also have to admit that the US covers for most of the worlds military. Most of nato and many Asian allies have very low defense spending, because the US will cover them. Most of the time when there is a global crisis or localized crisis the US is involved in one way or another.

we need to reel in the international shipping industry, the fashion industry, and also the global war machine

Believe you mean "modernize" and not "reel in," because ending international shipping would be catastrophic worldwide.

There's a lot if you look for it, recent developments in tidal are incredibly positive and we're absolutely going to see a rapid uptake in marine electrification as existing technology progresses through the market. Most people never really think about the resources used and pollution caused by small boats but one of the big destructive forces at play is the infrastructure requirements - small boats need big boats to supply their fuel stations.

Transitioning away from this system and instead using costal tidal generators to charge electric ferries and barges could be a total game changer in many areas, especially many of the highly trafficked and polluted tidal basins like in north Brazil, Nigeria, or island clusters like in the Philippines. Also the intercoastal waterways around the US and other leisure spots.

We're making great progress in many areas and I really think it's important to acknowledge this and cheer it on least we get so caught in a false sense of doom that we just give up.
