The Benefits of Clean Energy in a Nutshell

  2. 2. Why don’t we start with Subsidies? Wind & solar are subsidized by just about every country in the world The main rationale is that they produce “POSITIVE EXTERNAILTIES” which are benefits to society that are not captured in their market price
  3. 3. Specifically, wind and solar power reduce pollution, which reduces sickness, missed work days, and early deaths. Every wind farm or solar field displaces some other form of power generation (usually coal or natural gas). In our case we can replace the Site C dam……. Subsidies are meant to remedy this market failure, to make the market value of renewables more accurately reflect their total social value.
  4. 4. The question is, Are renewable energy subsidies doing the job? Researchers at the Lawrence Berkeley Lab have just produced a detailed report that contains all kinds of food for thought, both in its numbers and its uncertainties. You can see this on our blog at - 13 nobel prizes are associated with Berkeley lab
  5. 5. A quick side note! Just about every country in the world also subsidizes fossil fuels. Fossil fuels receive far more subsidies than renewables, despite the lack of any policy rationale whatsoever.
  6. 6. And now for the good news! From 2007 to 2015, wind and solar in the US reduced Sulphur Dioxide, Nitrogen oxide, and Fine Particulate Matter by 1.0, 0.6, and 0.05 million tons respectively; reduction of those local air pollutants helped avoid 7,000 premature deaths (the central estimate in a range from 3,000 to 12,700); those avoided deaths, along with other public health impacts, are worth a cumulative $56 billion (the central estimate in a range from $30 to $113 billion); wind and solar also reduced CO2 emissions, to the tune of $32 billion in avoided climate costs (the central estimate in a range from $5 to $107 billion).
  7. 7. wind and solar saved Americans approximately $88 billion in health and environmental costs over eight years.
  8. 8. Lets talk about Site C
  9. 9. $9,000,000,000.00 According to the National Ready Mix Concrete Association (NRMCA), Approximately 100 to 300 Kg’s of CO2 is produced for every cubic meter of concrete (2400 kg’s) According to the Site C website there will be Approximately 32 million cubic metres of excavation for structures, including the approach channel and tailrace
  10. 10. One can only assume that there will be 32 million cubic meters of concrete poured for those structures. This equates to approximately 64,000,000,000 (with a B) kgs of CO2 released into the atmosphere. (70,000,000 tons!) remember these numbers In fairness NRMCA says that as the concrete cures it absorbs about 33 to 57% of the carbon over 100 years
  11. 11. How much CO2 does solar produce Let’s say the BC government offered $9 billion worth of grants for solar installations and they gave them in increments of $10,000.00 as long as the client matched that amount That would be a total of 900,000 solar projects of 7kW or more if the client wanted to spend more than $10,000 (it would take 665,000 systems this size to equal the output of site C)
  12. 12. When a solar panel is produced there is approximately 5.4 grams of carbon released into the atmosphere and there would be 23,400,000 solar panels if everyone did a 7kW system That is 126,360 kgs (140 tons) of carbon released into the atmosphere. (93,366 kgs for 665,000 systems)
  13. 13. We haven’t even talked about the other issues? - what if this happens? This Photo by Unknown Author is licensed under CC BY-SA
  14. 14. I’m not against hydro power, in fact I think it’s amazing. I just don’t think we need another dam What about the prime farm land that will be flooded? What about the people and their homes? What will the actual costs be when construction is done? What about ongoing maintenance costs?
  15. 15. We need to consider our own footprint on this planet!
  16. 16. What you don’t see in the picture is this! I used to burn 250 litres of gas per month, now this powers 80% of my car
  17. 17. It also powers 100% of this car, the offices and the shop
  18. 18. We received $16,000.00 worth of incentives for these 2 cars and $0 for the solar. The BC government has announced they will provide a $5000 incentive for people top switch from Natural Gas heating to an electric heat pump. But no additional incentive for solar to offset the additional higher cost of heating with electricity.
  19. 19. Even without incentives; solar energy, converting from gas to electric appliances and electric vehicles make very good financial sense and the benefit to our environment is huge. Our company now saves an average of $800 per month in electricity and fuel. We have dramatically reduced our carbon footprint and it hasn’t changed the way we do business. In fact it has enhanced it.
  20. 20. WHY DO WE NEED INSENTIVES FOR RENEWABLE ENERGY IN BC? Aside from everything else I have said, The reality is that most people think that solar does not work in BC. We working against a stigma in this
  21. 21. Does solar work in BC? This client didn’t pay for electricity all year and he received a $630 check back from BC Hydro at the end of it.
  22. 22. Thank you very Much!
