The world's cheapest power source is scaling at warp speed, pushing coal, gas and nuclear aside.

      You can support it by using electricity, for water heating, laundry, dishwasher, when there is a surplus of solar power. Don’t give money to power companies that kill us, give it to producers of clean, safe, and peaceful energy.

    China is winning the race whilst the US is going back to beautiful coal and stolen oil.

      Electric motors and heat pumps are far more energy efficient than their combustion counterparts. Solar and wind electricity can be generated in situ or transported via cable. No need to power ships and trucks for fossil delivery to refineries or fuel stations. Thus we will end up with less primary energy.

        How does a heat pump helps you firing Portland cement, ceramics, melting glass and metal, fixating air nitrogen? And these are all 24/7 industrial processes.

          These are still big challenges, but very bright people already work on them. For example, Germany’s Hans-Joachim Schellnhuber, a top climate scientist, is working on climate-friendly buildings. Other research groups have worked on recycling concrete into more climate-friendly cement as a co-product of electrical steel processes.

          In cement production particularly: Pumps + co 2 capture = 5x efficiency in the process + negative carbon footprint

          Add renewables and voila, best cement factory in the world

      The race is about new energy. An old gas plant is still cheap to operate. But when faced with the decision of building new capacity, solar is cheaper and its not close. New gas energy is grinding to a halt.

      Electricity for heat pumps and moving vehicles is far more efficient than burning stuff. You need to look up the difference between energy and exergy. Electricity is 100% exergy, and can power heat pumps. Fossil fuels not.

        Do you know a heat pump which operates at 1400-1600 deg C?

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
