A picture can speak a thousand words and the chart above shows how solar installations have
exploded worldwide and all this activity has happened in just the last few years. Amazing growth that gives one optimism about what we can do when the chips are down.
The chart above clearly shows that all of the solar power that we've installed on the planet until about 10 years ago basically didn't amount to anything compared to what has been built in recent years. At some magical threshold, the price of solar per watt (in orange) hit some tipping point and installation exploded (the blue part), dwarfing anything from the past. And the beauty of having exponential growth on your side is that very quickly, even the current blue spike will look tiny. In 2020 or 2030 we'll look back on 2015 and it'll barely register as the beginning of the curve on the chart.
There is a grassroots swell of support for clean, green energy that has fought against the naysayers and obstructionists. There is no stopping this. We'll be getting our energy from the same resource that supplies our food and it will lead us to a safer, healthier future.
