Notes - On Bill Gates Articles & TED Talk, ways to fight climate…

- - - - Shows the Market That there is a need for the product
        
        More innovations are made, to make the product cheaper and reducing its environmental impact, etc.
    - - Companies purchase more then the average consumer and so have a bigger impact if they change to environmentally friendly products.
      - It can also, set an example, for the average consumer again, bringing down the purchase of products harmful to the environment.
        
        More innovations are made, to make the product cheaper and reducing its environmental impact, etc.
  - - - Energy Visualization
        
        Small town: 1 megawatt
        
        Mid-size city: 1 gigawatt
        
        The United States: 1,000 gigawatts
        
        The world: 5,000 gigawatts
        
        Average American house: 1 kilowatt
      - This question mostly comes up when thinking about electricity. It might say that an energy production facility is producing 500 Megawatts and you question how much that actually is.
    - - This Question, is very important due to space, on earth being limited and so if you want to slow down climate change, this space has to be used efficiently.
      - It is also, important for power plant or power generating facilities to know how much, energy they produce per square meter, which helps in determining which, energy production is more efficient.
        
        Estimates for Energy Production in different Ways.
        
        Fossil fuels: 500–10,000 watts per square meter
        
        Nuclear: 500–1,000 watts per square meter
        
        Solar: 5–20 watts per square meter
        
        Hydropower (dams): 5–50 watts per square meter
        
        Wind: 1–2 watts per square meter
        
        Wood and other biomass: Less than 1 watt per square meter
    - - When trying to find a solution for climate change, making a solution that tackles only one point of the processes in which CO2 might work, but other sectors also, require a lot of solutions. Also, all the sectors have to be brought down to 0 or very closely to 0, to stop climate change.
      - CO2 Emission distribution
        
        Making things (cement, steel, plastic) 31%
        
        Plugging in (electricity) 27%
        
        Growing things (plants, animals) 19%
        
        Getting around (planes, trucks, cargo ships) 16%
        
        Keeping warm and cool (heating, cooling, refrigeration) 7%
    - - cost is important, as it determines if people are even going to buy the product. It is also, important for there to be a reason, except it being green to buy it over the cheaper version, if the product is more expensive than the environmentally damaging one.
    - - This Question is important, to find out the importance of a solution. As an example, a company that might save 10 million tonnes of CO2 a year and that only once, is less beneficial to the environment, than a company that might save 5 million tonnes of Co2 and increasing that amount every year.
