The scoop: Cycling is a simple but effective way for individuals to reduce their carbon footprint. On a larger scale, cycling is an important tool in fulfilling the UN's Sustainable Development Goals (SDGs).
Facts and figures:
- 50% of all deliveries in metro areas can be completed by bicycle.
- Switching from a car to a bicycle saves 150g of CO₂ per kilometer. (UNEP)
- A 2015 Institute for Transportation and Development Policy study concluded that a dramatic increase (about 20%) in cycling worldwide could “cut carbon dioxide emissions from urban passenger transport by nearly 11 percent in 2050.” (bicycling.com)
- In 2019, direct greenhouse gas (GHG) emissions from the transport sector accounted for 23% of global energy-related CO2 emissions, with 70% of direct transport emissions coming from road vehicles. Case studies suggest that active mobility like walking and cycling could reduce emissions from urban transport by up to 10%. (UCI)
Bottom line: Cycling allows individuals to lead a healthier, more sustainable lifestyle. And when an entire society adopts cycling, it can profoundly impact the climate.

- In 1904, Tesla invented an efficient bladeless turbine.
- Tesla proposed electric power generation through geothermal, solar and wind energy.
- Tesla speculated on the existence of the ionosphere years before we discovered it.
Bottom line: Tesla imagined the world in many ways more like a philosopher than a scientist. But his scientific mind was as infallible as any. One thing is for sure: the modern world would be far behind without Nikola Tesla.

The scoop: El Salvador announced that Bitcoin is now legal tender. Citizens can pay taxes with it and stuff.
Why it matters: El Salvador is the first country to recognize a cryptocurrency as a legal form of currency. This marks a major shift toward government's view of decentralized financial systems, and a potential shift away from central banks.
The energy problem: We all know Bitcoin has an energy problem. To combat that, El Salvador plans to use geothermal energy from its volcanoes to produce cheap, clean energy for bitcoin mining. Let's see if they can build sophisticated infrastructure to match pent-up demand.
Bottom line: In the rush to make bets on the future of finance, governments around the world are responding with crypto plans for citizens.
Question: Will this push for legal forms of cryptocurrency help or hurt its climate impact in the long-run?
