That's very comprehensive, 100s of pages of technical and impact reporting. I'm not trying to undermine the project, was just curious and hoping for a ELI5 kind of thing.

When you divide the total emissions associated with a wind turbine by the amount of electricity it will produce in its lifetime, it works out at about 6 g of carbon dioxide for every kilowatt-hour (kWh) of electricity.1

By comparison, power generation based on fossil fuels involves burning more coal, oil or gas for every kWh of electricity, on top of the one-off carbon emissions from construction and decommissioning. For coal, this adds up to approximately 900 g per kWh.

Climate - truthful information about climate, related activism and politics.

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.
