LNG isn’t the answer, it is a stopgap solution. LNG = fossile fuel
Biodiesel can be used to power diesel engines.
Biodiesel can be made from used cooking oil collected from the many hawker stalls, coffeeshops and fast food restaurants in Singapore.

agreed lpg is now a stop gap fuel as its finite.
They cant get enough cooking oil, its a nice headline
One jumbo almost 200 tonnes of fuel for a long haul, was 200tonnes of cooking oil discarded in Singapore for each flight no, but sustainable fuel is actually part sustainable and part good old jet fuel. I’ll bet the woke think its 100%?
Plant based oil is being shipped worldwide now to make this headline. Lots being shipped from Australia to Europe.
We need a breakthrough in a new chemical for liquid fuels
When we start having carbon and co2 life cycles on products we can all see whats a headline and whats a step forward.
The goal is Net 0 Not eliminating petroleum entirely. It doesn’t have to be one or the other, it can be a combination of things. Just like how charging an EV on 20% wind is better than running an ICE in stop and go traffic, watering down different flavors of diesels with biofuel is still better than 100% jet fuel.
We don’t need a few people to be perfect when it comes to reducing impact, we need everyone to try a little bit.
This is not always the case.
For one, Clean Coal is a myth, and has never worked despite Coal lobbying and dumping billions into research.
Second:
Only a third of the windmill is burned, and even then it reduces emissions by 27%.
Roughly 75% of the blade material replaces the raw silica currently used to make cement. The rest replaces some of the coal used to fire the kilns.
Veolia claims 90% blade recycling by weight. About 65% becomes raw material for cement production. Another 28% becomes an alternative to coal in firing the kilns. Veolia says its recycling method reduces CO2 emissions by 27% compared to traditional Portland cement production.

So its not net zero its just cleaner than yesterday.
I have no problem with that, the worlds has been cleaning up for years where technology has polluted and so it should.
Cars are about the best example.
Coal power about the worst, but Germany still very keen on coal.
How about the carbon cycle of making the wind turbine blade along with burning it at the end?
Here is another carbon cycle, is it saving the planet or not?
Exactly, Eventually we will get there. In 1937 the record for a F-1 Pit stop was 33 seconds, today they do it in less than 2 seconds. Eventually, we may get to net Zero for carbon.
The blades are getting better. I do not have crystal ball.
blades are making the headlines for the wrong reasons but the glass industry globally has the issue,
There is lots being done as the boating industry booms, new materials are being used in small amounts that are either recyclable or from renewables.

You are talking about PSA Marine tugs, not jumbo jets, right?.
This is about GHG emission, not only local particle pollution.
The smoke from burning forests in Indonesia that is engulfing Singapore and Peninsular Malaysia at the moment is the last. As is the black smoke you see from ships and lorries etc.
CO2, methane and other Green House Gases are not visible by themself, but that is what is causing global warming.
No, Germany is not “keen on coal”, but it takes some time to get renewable energy enough to replace it.
Work in progress, aiming for “Net Zero” by 2045:
yes every plane talking off has 2 gallons of cooking oil mixed into 200 tonnes of fuel so flights are 100% green now.
Bio diesel has the same issue, they are burning the forests in Indo to plant palm oil to put in planes and diesels to reduce pollution.
Its not carbon neutral hence the EU has agreed to try to ban palm oil, good move.
At least somebody measured the carbon cycle.
Hurray,!!! you finally found something positive to talk about. Keep it up.

The EPA in America was created in 1970, has done great work. Led the world for many years.
Australia followed the model but gave it greater powers of enforcement.
Emissions are now political so its all gone green instead of black and white.
I have sold the same tree over and over for carbon offsets ( pay to pollute) its better than having your own gold mine.
Who is planting mangroves? One of the best tools to fight co2?
None, its all about headlines to fool the woke
Maybe its natural?
Carbon Dioxide
“The most surprising result, the authors noted, is that while carbon dioxide (CO2) emissions fell by 5.4% in 2020, the amount of CO2 in the atmosphere continued to grow at about the same rate as in preceding years. “During previous socioeconomic disruptions, like the 1973 oil shortage, you could immediately see a change in the growth rate of CO2,” said David Schimel, head of JPL’s carbon group and a co-author of the study. “We all expected to see it this time, too.””
This is a lively debate. The original article points out a contract vendor that failed to deliver the recycling service agreed and a mess has resulted. Now that would never happen in O&G right ? Oh. It does.
Well, run it in Texas Monthly anyway and spin it so it’s bad. Funny for a state which has a huge number of windmills.
Regardless of the microdisputes above, the conversion of millions of years worth of stored solar energy into heat, work and gases within a hundred or so years is seemingly problematic for the planet.
Not to worry, we can get a new one from that Walmart down Galliano way. Hence to heck with even worrying about thinking outside the box to solve some things like how to move ourselves and stuff around. In the meantime I’m headed to a nicely heated shower and some fresh washed clothes.

I often hear:
“Lithium mining is bad for the planet”
“Wind turbines kill birds”
“What happens to the old solar panels
These are issues of varying importance (e.g. wind turbines kill a tiny fraction of birds per year compared to cats, and kill fewer than global warming will). But the presence of these problems does not mean renewable energy is a bad idea. The net effect of moving away from fossil fuels is a benefit

Keeping cats inside is generally considered a good idea ( i don’t think they were killing many birds at sea where the turbines are proposed off NSW, plenty elswhere )
Now
The lithium mining issue and the old solar panels ?
Keep it simple, go nuke while the issues are sorted out with other sources.
They probably will be in time.

There is really only one cause of global warming: overpopulation!
There is really only cure: reduce the population.
We humans lack the foresight and political will to effectively reduce the population.
So, nature is going to do it for us. Global warming is one of nature’s mechanisms to reduce the size of the human herd.
We humans have interfered with routine natural mechanisms, famine and disease, to keep the ecosystem in balance. Humans are “winning” in the short run, but in the long run nature always wins.
The surviving human population will be much smaller, and then the next over population cycle will begin again.

WWIII?
Natural disasters, crop failures, famine, disease, droughts, wildfires, are most likely to reduce the population.
Human efforts or failures will probably have relatively little effect on population reduction.
Covid didn’t work
I hear feminism drops the birth rate (possibly the sex rate too).
