Per year it appears.

> The solar plant provides an installed capacity of 8.4MW with over 17,000 bifacial solar panels capable of capturing solar irradiance on both sides, maximising energy production.

> The wind park has eight turbines and a total installed capacity of 11MW, including a more powerful machine installed as part of an over-equipment project.

> The hybrid project is capable of producing up to 39.5GWh per year, enough to provide over 30,000 people with renewable energy. The hybrid complex will also help prevent the emission of approximately 18,000 tonnes of CO2 annually.

Please read this article - it's not that long, but will give you great insight.

The short of it is that this concern has been raised in numerous areas, and is just fearmongering. There are always alternate options or more reserves, and high prices promote the development of both.

For example we don't need rare earth magnets for EVs - most electric motors do not use rare earth magnets for example. Lithium reserves have doubled over the last 10 years, and batteries are one of the most fungible items in the green revolution - you can even make one from compressed air.

In short - don't listen to the fearmongers - their predictions never come true.

> Portugal seeks to have 80% of its electricity usage coming from renewable sources by 2026 > That’s up from 60% now, which is already one of the highest ratios in Europe

This is amazing news, and numbers which were unimaginable 10 years ago.

I think Portugal is helped by their terrain however. Hydro forms 40% of their renewable share, and they also have extensive pumped hydro for storage.

We know EV sales have hit 90% market share in Norway, but there has always been a question of whether they are an outlier and if the rest of the world will follow. Multiple European countries are now showing that Norway was just the forerunner and are rapidly following in their footsteps.

In December 2022, new passenger car registrations in Germany increased by 38% YoY to 314,318, the highest monthly result in 42 months. The most significant result was the massive surge of plug-in electric car sales, both all-electric and plug-in hybrid. In December, 174,126 new passenger plug-in electric cars were registered in Germany, 114% more than a year ago, and a new all-time record. The market share of rechargeable passenger cars in December amounted to 55.4%, a new record, far beyond the previous one of 39.4%, and a true sign of the times that plug-ins are now in the majority.

The reason behind the surge is largely related to the reduction of incentives for BEVs and elimination of incentives for PHEVs from January 1, 2023, meaning January numbers will likely be a lot lower, but there is little doubt that ICE cars are now legacy cars increasingly relegated to the second-hand market.

Notably, the UK also saw record numbers of new electric car registrations in December 2022, with 42,284 all-electric cars (BEVs) and 8,367 plug-in hybrids (PHEVs) registered. This led to a market share of 32.9% and 6.5% respectively or 39.4% combined. The total number of new plug-in electric car registrations in December was 50,651, an increase of 41% YoY. For the year 2022, more than 368,000 new passenger plug-in cars were registered, reaching an average market share of 22.8%. This is a new record and notably better than 2021 (305,281 and 18.5% share).

Given the 14-20 year replacement cycle of passenger cars, it appears likely by 2050 there will be no ICE cars on the roads at all, which should go a long way to meeting CO2 emission targets.

> In fact if we could produce our electricity about 2 times zones to the west and bring it to the place of consumption by HVDC cables, we could match the demand almost perfectly.

Imagine massive floating solar farms in the pacific ocean.

If you can trust chatgpt (which you cant really) about 51 acres of solar panels would be enough for the west coast duck curve.

One way to reduce the need for storage is to seriously overbuild capacity, like 7 times more than needed. That way you get good resilience to variability and you need much less storage.

In good times you use the excess electricity for carbon capture for example.

This is a key line:

> it is incomprehensible how IRENA can expect annual global PV installations to plateau at around 440 GW per year of new solar from 2030 to 2050.

The growth of solar has been exponential, but for some reason people always expect it to suddenly become linear.

The idea is to use excess solar energy heat and store the transfer fluid to generate electricity at night.

Apparently, trough CSP is about 20-40% efficient, and solar cells are about 20% efficient, and turning electricity to heat is 100% efficient, so if the solar cells are 1/2 the price of the troughs, they would be cheaper than the troughs in generating heated fluid for storage.

Sure doomster. Do you expect to be alive in a year? If no, quit your job and go travelling.

If you expect to be dead in 10 years, stop paying into your pension and retire.

If you expect to die in 20 years, you know, shit happens. It could happen to any of us any day.
