Have you heard the news? We're in a clean energy revolution. And where I live in Berkeley, California,
你們看新聞了嗎？我們正在進行清潔能源革命。我住在加利福尼亞州伯克利市，
it seems like every day I see a new roof with new solar panels going up, electric car in the driveway.
幾乎每天我都會看到新的太陽能板被裝在屋頂上，電動汽車停在車道上。
Germany sometimes gets half its power from solar,
德國一半的電力來自于太陽能，
and India is now committed to building 10 times more solar than we have in California, by the year 2022.
印度計劃在2022年完成的太陽能板數量，是加州的十倍。
Even nuclear seems to be making a comeback.
甚至連核電都重返舞臺了。
Bill Gates is in China working with engineers,
比爾·蓋茨正在中國和工程師們合作，
there's 40 different companies that are working together to try to race to build the first reactor that runs on waste,
他們來自超過40家不同的公司，互相競爭，嘗試建造第一個以廢材為原料的反應堆，
that can't melt down and is cheaper than coal. And so you might start to ask:
永不融化，比燒煤還便宜。所以，你可能會問：
Is this whole global warming problem going to be a lot easier to solve than anybody imagined?
“全球變暖問題是不是比大家想象中要更容易解決？”
That was the question we wanted to know, so my colleagues and I decided to take a deep dive into the data.
這也是我們想知道的，所以我和我的同事們開始調查數據。
We were a little skeptical of some parts of the clean energy revolution story, but what we found really surprised us.
之前我們對能源革命中的一部分故事有所懷疑，但是最終的發現卻讓我們大吃一驚。
The first thing is that clean energy has been increasing.
首先，清潔能源的使用率一直在升高。
This is electricity from clean energy sources over the last 20 years.
這是過去20年間清潔能源的總發電量。
But when you look at the percentage of global electricity from clean energy sources,
但是當你看到全球范圍內清潔能源總發電量占比時，
it's actually been in decline from 36 percent to 31 percent. And if you care about climate change,
事實上，這個比例從36%下降到了31%。如果你在意氣候變化，
you've got to go in the opposite direction to 100 percent of our electricity from clean energy sources, as quickly as possible.
你一定要盡快做出改變，使用純清潔能源電力越快越好。
