That pledge by the group of wealthy nations -- responsible for around 80 percent of greenhouse gas emissions -- is in line with what experts say is possible and necessary to keep the world's climate goals in sight.

”What experts say…” Translation: What we journalists, editors, and media company owners want you to hear - after sifting out those things that experts actually said which don’t always fit the “world will end on (see Greta’s latest prognostication)…” climate hysteria narrative.

As long as India and China are increasing their reliance on burning coal for power, can we solve this problem?

Don’t trees have a thing for CO2?

Plants flourish with higher levels of CO2. Fossil records attest to this.

We cannot and should not pretend we can all the while damaging our economy and lowering the standard of living of ordinary people. Elites make sure THEY don’t suffer.

Japan needs more offshore wind turbines. Tidal generator. Geothermal. Smartgrid.

I'd put solar-power and fusion power on that list, too No need for an incomplete list is there?

Japan already has too much solar power. Fusion power reactors are not commercially available.

Lol. First up, I'm entitled to my comment with you jumping all over it Again. Ok!!

Fusion power reactors are not commercially available.

Second, I know I have a Chemical Engineering degree from Newcastle Uni and read up on the latest developments related to that area of expertise, pet.

Just because they aren't commercially available doesn't mean they don't need fusion power reactors, does it?

Good night.

I don't stop you from your opinion and I can have mine. Fusion reactors are still some years away. Once they become available they have to be constructed. Probably 2050 at least before we see them.

80% of 47 prefectures have problems with solar power plants. The solar panels were a panic reaction to 3/11 and were not properly planned and thought out.

Thanks. You saved me from googling. Just what Japan needs, right? Nuclear fusion reactors

In your opinion what is the earliest date for fusion reactors plus 10 years to construct one?

0 ( +1 / -1 )

What will be the cost to construct a fusion reactor? Current estimates are $22 billion. They will be ten times more expensive than nuclear energy.

Yes, it's literally what we all need.

Japan's problem with power generation is that natural energy cannot cover the current amount of thermal power generation.

Solar power generation involves environmental destruction, and opposition from local residents is growing louder.

Offshore wind turbines require detailed maintenance, and there is an undeniable shortage of manpower. The impact of tidal power generation on fisheries is still unclear.

Geothermal power generation inevitably faces opposition from the hot spring industry. It's not going to be like Indonesia.

Currently, the best way to reduce CO2 emissions in terms of environmental costs is to shut down thermal power, coal, and LNG, and restart nuclear power generation.

Nuclear fusion reactors are expected to be the next generation of power plants, but there is still a long way to go.

Even with Japan's efforts, CO2 emissions will not decrease much, so unless countries that emit large amounts of CO2, such as the United States, China, and India, take measures, the world environment will not change. Whether or not the rise in average temperatures can be halted depends on these three countries.

In my opinion, fusion power should be on wallace's list of power sources Japan needs. No reason for an incomplete list is there?

There are also molten salt nuclear reactors without the same danger of meltdown, though not completely production ready. I've also heard good things about the latest generation of water cooled reactors, although I don't know whether they are completely safe from earthquakes.

Japan needs more offshore wind turbines.

They seawater and salty air are not too kind to offshore winter terminals. The underground transmission cables (20% of the overall cost) are often replaced after a few short years and don’t usually last as long as the turbine itself which is only good for about 10 years. Yes the capacity factor is a bit higher but overall too expensive to maintain and we all know the damage it does to sea lives and the fishing industry.

Looks like we need 400% increase in annual renewable energy capacity in basically 6 years. Like I say with software, "everything is doable with time and money.". Problem is that both are finite. Spend on energy, particularly another country's energy means less for your domestic consumption.

Given most advanced countries spend roughly 3/4 or more on fixed payments, it will be a massive change in spending that frankly will not happen.

Prepare yourself and family as you see fit.

80% of 47 prefectures have problems with solar power plants. The solar panels were a panic reaction to 3/11 and were not properly planned and thought out.

And before solar power is trashed, some people have their minds on bigger and better things.

Tim Peake astronaut has backed the idea of solar farms in space, saying the concept is “becoming absolutely viable”.

This is a key point.

Actually fossil fuels will keep getting more expensive due to limited supply, while renewables' will keep getting cheaper as the tech improves and we find new substitutes for their construction. In 50 years or so we may have more energy supply than we (currently) know what to do with!

And with fossil fuel prices and energy insecurity spiking after Russia's invasion of Ukraine, the IEA expects an unprecedented increase in new renewable energy capacity of around 30 percent in 2023.

Japan needs to use renewable energies which are available now or over the next ten years. Fusion and molten salt reactors are not available nor are solar panels in space.

Many European countries are using offshore wind turbines.

Is CO2 actually a pollutant, as the article suggests?Don’t trees have a thing for CO2?

Even if you don't think CO2 is a pollutant, there's no doubt whatsoever, we still need energy innovations.

There has been NO innovation in energy for 6 decades, oil was $2 a barrel in the 70ties, it's over $100 today. Not even the ponzi housing investments sector can compete with this.

https://www.researchgate.net/figure/1-Nominal-and-real-monthly-Brent-crude-oil-prices-1970-2012_fig2_334696897

But, yes it's a pollutant, because excess CO2 warms the planet. It's that simple. I'm an investor in fossil, have had Exxon stocks for 1.5 decades, because I know there are people who sticks their head in the ground and refuses to innovate. Then are there greedy fat cats that says the world need more roadblocks to actual CO2 reduction as well, ie carbon reduction certificates (tax) instead of actual reduction.

The world need to innovate and transition. It's that simple, until I see evidence of this, I'm going to be invested in fossil, it's my retirement gravy train.

CO2 is a greenhouse gas - too much of it, and ya get the "greenhouse effect" and runaway heating loop

Check out planet Venus - why it's the hottest planet in our solar system because of it (not Mercury the closest planet to the sun, or the giant gas planets full of radiation - Venus heat has them beat because of CO2)
