    This is wrong. In the USA, there are also subsidies and mandates for ethanol.

    But my state, Georgia, is relatively green:

    Natural gas accounted for 41% of Georgia’s net electricity generation in 2018, the state’s four operating nuclear reactors accounted for 26%, coal accounted for 25%, and renewable energy, including hydroelectric power [19 hydroelectric dams], contributed 8%.

    Natural gas is better than coal, first because it produces less CO₂ which is apparently important, and second because it enables combined-cycle plants for much greater efficiency than the Rankine-cycle–only coal. Much of the natural gas can be exploited because of the privately owned fracking technology not government subsidies.

    Georgia is also starting two new nuclear reactors.

    Small beer when compared to the $US 5.2 trillion global subsidies for fossil fuels, thought that number is three years old now, so expect it to have grown.
    So what's your excuse? To run like the devil's chasing you.

    Technically, rooftop PV with battery backup will blackout-proof your home. PV alone will not, as output shuts down automatically in a blackout to de-energise the transmission lines during repairs.

    I oppose all subsidies.

    Yes, it makes sense to have batteries as well. What kilowattage is your system?

    Only 1.8, which was the standard offering at the time

    You must have had this for a while then. Is it still working well and covering all electrical requirements? Sounds like the 15.8 kW I have been quoted for is overkill. 6 kW seems to be the US average home installation these days.

    David Attenborough weighs in on Australia's bushfire crisis
    7 News, Friday, 17 January

    David Attenborough says the "moment of crisis" has come in the fight against climate change, warning that governments' targets for decades in the future are not enough to save the planet.

    Noting the destruction being caused by Australia's wave of bushfires, Attenborough criticised Canberra's approach to climate change, saying the government's support for coal mines showed the world it did not care about the environment.

    The British naturalist also called on China in particular to reduce its carbon emissions, saying he thought other countries would follow if China set a lead.

    ... "This is an urgent problem that has to be solved. And what is more is that we know how to do it - that's the paradoxical thing - that we are refusing to take steps that we know have to be taken." ...
    So what's your excuse? To run like the devil's chasing you.

    That makes a change.

    Still in good nick but too small to run a household. I'm still paying about $450 a year for power. 5 kW is a good size; 6.6 is a common offering nowadays.

    15.8 is humungous.

    BlackRock bows to pressure and begins exit from coal investments

    The CEO of BlackRock, has responded to intense pressure from NGO’s, investors and commentators and announced the US$7 trillion asset management company will begin “exiting investments that present a high sustainability-related risk, such as thermal coal producers.”

    Sustainability as BlackRock’s New Standard for Investing

    ... Over the past few years, more and more of our clients have focused on the impact of sustainability on their portfolios. This shift has been driven by an increased understanding of how sustainability-related factors can affect economic growth, asset values, and financial markets as a whole.

    The most significant of these factors today relates to climate change, not only in terms of the physical risk associated with rising global temperatures, but also transition risk – namely, how the global transition to a low-carbon economy could affect a company’s long-term profitability. As Larry Fink writes in his 2020 letter to CEOs, the investment risks presented by climate change are set to accelerate a significant reallocation of capital, which will in turn have a profound impact on the pricing of risk and assets around the world. ...

    Thermal coal is significantly carbon intensive, becoming less and less economically viable, and highly exposed to regulation because of its environmental impacts. With the acceleration of the global energy transition, we do not believe that the long-term economic or investment rationale justifies continued investment in this sector. As a result, we are in the process of removing from our discretionary active investment portfolios the public securities (both debt and equity) of companies that generate more than 25% of their revenues from thermal coal production, which we aim to accomplish by the middle of 2020. As part of our process of evaluating sectors with high ESG risk, we will also closely scrutinize other businesses that are heavily reliant on thermal coal as an input, in order to understand whether they are effectively transitioning away from this reliance. In addition, BlackRock’s alternatives business will make no future direct investments in companies that generate more than 25% of their revenues from thermal coal production. ...

    Mitigation or adaptation? When it comes to climate change, it's not a case of either/or

    Here's a ridiculously extreme best case scenario: everywhere in the world, we immediately cease all human made CO2 emissions. Right now. No emissions. Forevermore.

    Great! Problem solved! Right? Well, not quite.

    Climate change is a long, heavy, slow moving train crawling across decades. Even if we pull the emergency brake right now, we're not stopping for a while yet.

    I mean, in terms of warming trajectories, ceasing all emissions immediately would be a very good thing to do. The best science currently estimates that under this super extreme best case scenario we could probably keep warming to 1.5 degrees Celsius over pre-industrial levels.

    But, even so — and especially if we shoot past 1.5 degrees and then 2 degrees, which is where the current trajectory takes us — the train has a hell of a distance to travel before it grinds to a halt.

    Whatever we do from here, we've locked in at least some amount of warming — and the climate impacts that come with it.

    We're already seeing these impacts. The devastating fire season we're currently choking our way through has played out against a background of just 1 degree of warming.

    Things are getting worse before they get better, and we need to be prepared. This is why adaptation is an essential component of any effective climate change strategy. ...

    I'm sure there'll be many similar claims, but that's not a serious scientific argument against global heating.
