Why is the price of oil so low now? In fact, why are all commodity prices so low?
We need a speed limit for the internet.
It would make a lot of sense to restore this old way of warming, especially since modern technology has made it so much more practical, safe and efficient.
Cooling people by increasing local airflow is at least ten times more energy efficient than refrigerating the air in a given space, and it also adds the benefit of a personally controlled thermal environment.
Despite technological advancements since the Industrial Revolution, cooking remains a spectacularly inefficient process.
“It is a confusion of ideas to suppose that the economical use of fuel is equivalent to diminished consumption. The very contrary is the truth….no one must suppose that coal thus saved is spared-it is only saved from one use to be employed in others”.
Digital fabrication is praised as the future of manufacturing. While CNC machines have been embraced by many…it’s important to consider the very high energy use of digital machine tools.
As a species, we must learn to live within the physical limitations of the biosphere. In the electric energy sector, this requires reversing the worldwide trend of ever-expanding electricity supply grids carrying energy vast distances from more and more large, centralized power plants. “Capping the grid” is a crucial step toward reducing greenhouse gas pollution and increasing the percentage of electricity generated by renewables.
The natural gas industry has promoted shale gas as a source of energy independence. In this segment of the Delaware Riverkeeper Network’s Shale Truth Interview series energy industry analyst Arthur Berman says efficiency and changing everyday behavior are the keys for the United States becoming energy independent.
As energy consumption for transport in cities is expected to double by 2050, IEA report sees potential savings of up to USD 70 trillion
The UK Government is committed to cutting 80% of greenhouse gas emissions by 2050 – since 50% of our energy is used by our buildings, and 25% by our homes, the target is for every home to be ‘carbon neutral’ by 2050. In Shrewsbury this equates to 2,000 homes being refurbished each year for the next 37 years, saving 60,000 tonnes of CO2e each year in the process.
