End of the world

So yeah you may think the climate is screwed and it kind of is but we can fix it how for the last 250 years we've gotten really good at turning coal oil and gas into i phone heart surgery and all the other nice things in modern civilzation but coal oil and gas released a lot of carbon into the atmosphere and all that carbon has warmed our planets about one degree celsius so far and the more we add the warmer it's going to get in the simplest terms modern civilization is basically a 17 tera watt light bulb plugged into a coal power plant but not everyone on earth is plugged in  yet and as the billions of people in places like india and china start to use as much energy as the us and europe we're going to have to replace that light bulb with one that runs it something more like 30 to 50 terawatts so not only  do we need to find a way to gernate electricity without putting more carbon in the air that source also has to offer atleast twice as much energy as we use today imagine if you willl that scientists discover magical glowing ball hovering near us in space that transmits free energy to earth at the speed of light oh wait  sorry that already exists but is the sun enough well the sun is basically a tooo trillion terawatts hydrogen powered fusion  reactor and if we could some how surround it with solar panels and capture all of its energy at even just ten percent efficiency we could power civilization a trillion times the size of our own and yeah that might be an interesting long -term goal but it doesn't really help our current situation does it so more relistically of the 100 trillion terawatts only about 90,000 make it to earth surface and with our currently an available technology if we really really wanted to we could only capture about one sixth
Of that  but one sixth of 90,000 is 15,000 terawatts that's enough to power is thousand current human civilzation or just power the one we have well into the future using a tiny fraction of what of what the sun provides so why don't we do that well it's not like i can just plug into the sun it only shines on half the planet at a time and we're not great at storing electricity for the other half  plus even after you solve these problems the tecnology is just expensive but what is expensive really mean fossil fuels seem cheap but we're only paying half the bill the rest is basically a loan from the climate so depending on wheather we want to pay now or later there's whole range of possible ways forward on one end  of the solar system we make emitting carbon  expensive which makes it more affordable to build out our sweet solar infrastructure but also means we'll need to live in how about houses needed by our own flatulence spend out free time holding hands and making awesome open sweaters for our palms on the other end of the scale we keep carbon cheap turn all the fossil fuels and live in fortresses until we upload our minds to facebook and learn a rabot figure out how to clean up the mess i mean i guess it could also be something in between those two extremes but the point is if we want to fix the climate we just have to get better at turning sunlight into civilzation
