God has given us so many gifts, we tend to forget... for example, I like this article (which is not unique, though fossil fuel funded etc sources won't want you to know!) that indeed "shifting the World to 100 percent clean, renewable energy as early as 2030: here are the numbers" IS possible as "most of the technology needed to shift the world from fossil fuel to clean, renewable energy ALREADY EXISTS." (my emphasis, and this fact is contrary to some of the fancy suggestions regarding options on fossil fuel (e.g. so-called 'carbon capture & storage' - sound nice, but NOT proven beyond lab). The 'only' things that stops us is "implementing that technology requires overcoming obstacles in planning and politics." Might help to remind people that of the 100 biggest economic entities, MORE THAN 50 are COMPANIES (NOT countries!), and that of the 10 biggest companies, 7 sell cars and/ or oil... money talks & big money talks a lot...
