Renewable, Sustainable, Clean? An Overview of Carbon-Free Energy

March 29, 2023

In 2022, about 30% of the world’s energy came from renewable sources, with the US lagging behind the global average at 20%. But in 2021, the Biden administration set a target for 100% of US power to be carbon-free by 2035.

Carbon-free energy refers to the production of electricity in ways that don’t generate greenhouse gasses. Renewable energy, on the other hand, refers to electricity sources that are naturally replenishing. The two are often used interchangeably, but while many carbon-free energy types are also renewable, like sun and wind, others aren’t, like nuclear and large hydropower plants. But does carbon-free, or even renewable necessarily mean sustainable, clean, and safe? With such a range of approaches, the answer is: it depends.

How to Honor Indigenous Foodways in your Garden and Kitchen

March 21, 2023

Colonialism in the USA wreaked havoc on indigenous traditions and cultures around food production and preparation. For many tribes, bison were the foundation of society. But bison were massacred by settlers almost to the point of extinction, for sport, skins, and to wage war against Native Americans by destroying their main food source. As indigenous people were displaced from their land, they lost their ability to cultivate and gather traditional foods.

Forced cultural assimilation through boarding schools halted the transfer of knowledge. And a broader shift toward industrial farming, characterized by the use of mechanization, chemicals, and genetically modified seeds has led to the loss of crop varieties and pollution of land and water. But through food sovereignty efforts across the nation, indigenous people are bringing back traditional ways of doing things.
