Five questions to ask in every climate conversation - How much is this going to cost?
8 important questions on Five questions to ask in every climate conversation - How much is this going to cost?
What is the main reason that the world emits so much greenhouse gases?
- Our current energy technologies are the cheapest ones available, which means that if we want to get zo zero, it will cost something.
Can you explain why most of the zero-carbon solutions are more expensive than their fossil-fuels counterparts?
- The prices of fossil fuels don't reflect the environmental damage they inflict, so they seem cheaper than the alternative.
The size of the Green Premium depends on what you're replacing and what you're replacing it with. The cost of zero-carbon jet fuel isn't the same as the cost of solar-generated electricity. How can you explain this?
- For an example = the average retail price for a gallon of jet fuel in the U.S is $2.22. Advanced biofuels for jets, to the extent they're available, cost on average $5.35 per gallon. The Green Premium for zero-carbon fuel, is the difference btween these two prices, which is $3.13: a premium of more than 140%.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
Green Premium can be negative, which means that green can be cheaper than fossil fuels. How can you explain this?
- In some places, you can save moning by replacing natural gas furnance and air conditioner with an electric heat pump.
- For an example = In Oakland, doing this will save 14% of heating and cooling costs, while in Houston the savings amount to 17%.
The different premiums, help us answer various questions. How can you answer the question: "Which zero-carbon options should we deploying now?"
- The ones with a low Green Premium, or no premium at all.
The different premiums, help us answer various questions. How can you answer the question: "Where do we need to focus our research and development spending, our early investors, and our best inventors?"
- Wherever Green Premiums are too high, because the extra cost there will keep us from decarbonizing, and where there's an opening for new technologies, companies and products that make it affordable.
Green Premium can act as a measurement system that shows the progress we're making toward stopping climate change, what does it show?
- The Green Premiums gives information about measuring the cost of getting to zero, and shows us where we need to innovate.
DAC would be an extremely inefficient method for solving the carbon problem, why is that?
- It's not clear that we could store carbons safely: there's no practical way to collect $5.1 trillion a year and make everyone pays their fair share.
- We'd need to build more than 50,000 DAC plant to manage the emissions we're producing.
- DAC doesn't work on methane or other greenhouse gases, but only on carbon dioxide.
- It's the most expensive solution: in many cases, it will be cheaper not to emit greenhouse gases.
- We can't wair for a future technology like DAC to save us, we have to start now.
