Elon Musk has just announced that Tesla will no longer allow buyers to pay in bitcoin. Why is this relevant to a wildlife and environment blog?
Tesla is there to transition the world to sustainable transport, as a goal. of the roughly 4.1 trillion kwh of electricity used in the USA last year roughly 500 went on bitcoin (roughly 1 in 8) or 13%.
Studies over the last few years show that 80% of of people are open to eating meat grown in bioreactors.
Why is this good news? Well one of the important advances with this meat is that it is thought that it could be created with a similar carbon footprint to lettuce.
Continue reading “Lab grown meat saw funding increase 6 fold during 2020”The need for America to cut it’s carbon footprint by 50% in the next decade under biden’s plan has been attacked to absurd proportions.
Republicans have been arguing against doing something about climate change for decades. It should therefore be borne in mind that the speed of cuts necessary now has been made necessary by previous republican governments. Now this has to be remembered that this did not come from something Biden said, and in there more honest moments some republicans will admit this, unfortunately for the time being though it is clear that the noisy republicans are all in with this fake attack.
Humans eat between 1-2kg of food per day, so each person consumes roughly 1.2 tonnes a year. That means that one billion tonnes of food could feed half of China or India or alternatively the next 3 biggest countries – the USA Indonesia and Pakistan.
Another way of thinking about it, is that if humanity ceased wasting food tomorrow, there would be enough to feed the whole planet completely.

The industry as obviously attacked this, in part by pointing out the rules demanding that all cars be practically clear of emissions by 2025 will rule out clean fuels such as liquid hydrogen.

There is no requirement as to how long technology is required to last. In the past, that has perhaps been less noticeable, as the advance in the capabilities has been so fast, that an upgrade generally became desired long before the product wore out.
However, there has been an alarming trend which has seen manufacturers removing manuals to allow products to be serviced, and or sealing parts of the product, so that batteries cannot be replaced or in some other way making DIY fixing hard or impossible.
Continue reading “The EU is bringing in laws that require products to last for a decade”Thames water in London UK is hoping to use excess heat from sewage treatment plants to provide the warmth needed for 2000 homes in Kingston-upon-Thames.
What normally happens, is that once the water has been fully treated, it is returned to the river. The problem with this, is that the water is at a higher temperature than the river, and this is not good for its ecosystem.
Continue reading “Using sewage to heat homes?”A new system can transform thousands of hills in the UK into large batteries. A team of engineers have developed a system which would allow Hydropower to store and release power within gently sloping hills and without the huge dams currently needed.
The idea of these small hydropower systems, is that we could build many of these tiny dams for far less than just a few large ones. More importantly, it would come with far less negative issues to those that come with historic large dams (for instance the proposed dam which threatens the future of 8th great ape species the Tapulani Orangutan).
Continue reading “Could many hills in the UK become the batteries of tomorrow?”How can we cut the carbon cost of aviation? There are several possibilities. It is unfortunately unlikely that battery power is ever going to be able to replace fossil fuels on long haul fights (I hope to be proved wrong). Easyjet is aiming to be flying a single isle battery powered plane on 80% of its routes by 2040, and is hoping to be flying routes under 500km on battery planes by 2027 (they are well on the way to this target).
Continue reading “While great progress has been made in greening much of the worlds industries, aviation is one of the few that has made little progress”These statements have been made before, however the Chinese president has reaffirmed them over video-link to the UN general assembly. Currently responsible for around 28% of world emissions this is highly encouraging.
In the past China has agreed to its peak emissions point, but not to its carbon neutral point.
Continue reading “China has stated that they will aim to hit peak emissions by 2030 and carbon neutrality by 2060”
