- Using old data - the price of renewables and storage technology have fallen through the floor but bad actors are quite happy to use outdated numbers to convince you that they're not cheap
- Ignoring existing downsides - renewables have issues and we shouldn't forget that, but it's easy to forget what we're replacing. e.g. Lithium mines are environmentally unfriendly, but you dig it out of the ground and turn it into a battery once (and bonus - it's recyclable). Oil and gas must be continually dug out of the ground and burned
- But China... - I don't think most people realise quite how quickly the rest of the world is pushing on with renewables
Maybe I’m too optimistic :)
The rub with "solar is cheaper" is that those values are almost always calculated using an ideal environment. Solar is cheapest when you are using flat barren land in Arizona where an acre costs $500, the sun shines 330 days a year, you are bulk buying 750 MW of panels, and the bureaucracy is a single rubber stamp. Those are the numbers that ultimately trickle to headlines.
Things get much more complicated (read: expensive), when you are in the North East, an acre costs $12,000, the sun shines 170 days a year, you're bulk buying a few dozen MW of panels, and the bureaucracy is 6 different government bodies full of permits and assessments.
In that situation, a gas plant that produces 10x more power on 10x less land becomes very appealing to people who are already getting crushed by soaring electricity bills. (My take: we're just going to have to deal with higher costs).
So I am all with you on abandoning fossil fuels, but to someone who is firmly in gas camp, they will have legitimate ground to stand on when balking at costs. "It's cheaper" is unfortunately not all encompassing.
And not buying something tends to be cheaper than buying :)
This means that millions and millions of machines have to be maintained, shipping lanes have to stay open, infrastructure has to stay profitable, distribution has to stay easy and cheap. The web is invisible to the end user, but it is massively complicated and expensive to upkeep.
Solar, once you have the panels you have to clean them every once in a while, and replace a failing panel every once in a while. But they produce for ~30 years after being made once.
So it’s funny to argue about environmental waste in this way. It’s an issue, but everything in a solar panel can basically be recycled and we are seeing the facilities start to come online as the first wave of PV panels starts dying off.
1. Take statistics from any of these excellent solar power plants for, say, five years time span
2. Find the worst week in terms of energy production in these statistics
3. Explain to the renewable energy skeptic how this 20+ times drop in productivity will be compensated for users
4. The skeptic is successfully convinced and becomes a renewable energy proponent
