I believe that the time is drawing nearer and nearer when we as a world have to shift over to renewable energy. This switch is already happening right now with the development of more efficient and more cost-friendly infrastructure. But, for the most part, we are still reliant on coal and oil to power our homes. I think that one thing that we as a world can do to shift from fossil fuels to renewables is stop giving big oil and coal companies money through investing. BlackRock, one of the biggest financial institutions in the world recently announced that they would not longer be investing in coal. BlackRock has almost 160 billion dollars in assets, and so this decision will hugely impact the coal industry. I also think that one way that people can supplement their power is by installing solar panels on their roofs. Solar panels is a cost efficient way to pay less for power, and it also minimizes the amount of fossil fuels that are burned for power. I think that we as a world need to wake up to the crisis that is before our eyes and act. Our President resents the fact that climate change is real, but the fact is that without the financial support of the government, we will not be able to make the switch. So, therefore, even though we are already making big steps towards a clean energy powered world, we need to think bigger and use all the resources at our disposal to bring down fossil fuels and switch to a completely green and renewable energy system.

I totally agree with this. The problem is that so much infrastructure is based in coal, and that people are so resistant to change. Even though much of the changes that need to happen to transition to renewables could be executed relatively seamlessly, many of the people in power at the moment are working tirelessly against it at the moment. You had mentioned President Trump, someone surrounded by people with a direct stake in the oil and coal business. This is an issue only exacerbated by intense lobbying from coal companies. Just under $125 million was spent by oil and gas companies in 2019 alone(1). Robert Murray is an example of this. He owns Murray Energy, and is a huge proponent of coal, ignoring its short and long term health risks and working with officials, such as President Trump, to keep the coal industry alive(2).

i'm some what iffy on how reliable renewables are, although i do think we should use it it should not be our main source of power if anything it should be a backup energy source. the reason that renewables like wind and solar are so unreliable is that there will not always be wind and it won't always be a sunny day. take germany for example there a lot of there power comes from renewables and because of this when there is no wind and its cloudy the power grid under performs and you can have a huge amount of your power generation under perform but in 2017 this happen and germany had to put up with mass blackouts the dailycaller said "Germany’s power grid almost collapsed in January due to poor performance from wind turbines and solar panels" the same goes with energy surpluses will go with germany as the example again. in 2016 germany had so much power that they had to start paying people to use more electricity germany also sells there energy to other countries when this happens. all in all I think that nuclear is better for generating power

adding to OMuchmore's point, I think that not only is there so much infrastructure in place which helps the coal industry, there is comparatively so little infrastructure for the alternative, that is the renewable energy business. Coal has been around for so many years that it is so heavily engrained in our society today, and I think that is why it is so prevalent and hard to get around. This makes me think of Australia's coal business, which has been around almost since the white man came to the land, and they have been mining ever since. Australia doesn't want to get rid of the coal business, as it helps the economy so much and it makes so many jobs. Things like this make it very hard to get rid of coal and progress into other ways of clean, renewable energy.
