Zero is the new hundred. Designing and operating a home that generates as much energy as it uses used to be a theoretical concept. Now it’s becoming a reality. Some homes are also catching as much water as they use. Pricey? Sure. But not as pricey as you might think. We’ll discuss real homes that are exploring the boundaries of efficient living without reducing comfort.

San Francisco aims to produce zero waste by 2020. Is that really possible in a city with a booming economy and growing population? The city is ahead of the curve but policy, culture and psychology need to come together to reach the finish line. Other cities and universities are joining in and shaping the habits of big institutions and future generations.

In addition to talking trash, at this event Climate One staff will invite others to join them in the 5-Day Trash On Your Back challenge. Will you join us in carrying on your back in a plastic bag all the items you would otherwise put in landfill? We will compost and recycle items that Bay Area citizens devoutly place in those streams. Everything else goes into the bag and on your back. Take it to work, on your commute, and to that soccer game. Yep, there is no “away.” Snap a photo of your experience and share it on social media. On April 22nd, those who complete the challenge will gather at The Club to weigh their bags, share their stories, and exchange high fives. Are you in? Join us on April 15th to get started.


The speakers and audience will be videotaped for future broadcast on the Climate One TV show on KRCB TV 22 on Comcast and DirecTV.
