I am a tech geek from Austin TX (USA), living on the country side in Austria and devote most of my time to my girlfriend, my company, my students and different projects.
After building my own smart meter using 4$ in parts I started checking my electricity usage every day, which made me realize how expensive it is to heat your home. Especially since all heat and warm water in my low-energy house is made with electricity. I do have 4.8 kwp solar panels on my roof but in winter they don't cover too much for obvious reasons.
隔壁 Westin Building Exchange 的地址是「2001 6th Ave #300, Seattle, WA 98121」,辦公室則是在「2040 6th Ave, Seattle, WA 98121」,無論是從地址上看,或是 Google Maps 上可以看,都可以看出來兩棟就在旁邊而已,拉管線就簡單很多了。
The ordinance, passed unanimously by the city’s Board of Supervisors, extends an existing California law which requires 15 percent of roof space on new buildings to be “solar ready” — available and unshaded. That ordinance applies to residential or commercial buildings 10 stories or shorter.
也就是說,可以是太陽能的發電,也可以是太陽能集熱的設備:
Under the new ordinance, which will go into effect in 2017, new buildings need to have solar energy of some kind installed, either electricity-generating panels or solar heating units.
希望在 2020 年達到 100% 再生能源的目標:
San Francisco took a major step toward its own goal of meeting the city’s electricity demands with 100 percent renewable energy by 2020.
這成為美國第一個主要城市通過這樣的規範:
This week, San Francisco became the first major U.S. city to require all new buildings to have solar panels on their roofs, according to Scott Wiener, the city supervisor who introduced the bill.
