The World Set a New Record For Renewable Power in 2017, But Emissions Are Still Rising (qz.com)

In 2017, the world deployed an ever-expanding amount of solar and wind power, setting a new record for renewable-power capacity added to the grid. From a report: In fact, the money spent on renewable installations was more than twice the sum spent on nuclear and fossil-fuel power, according to the annual Global Status Report published by renewables policy group REN21. Over the past 10 years, global installed renewable-power capacity, which includes hydropower, has doubled.

That growth, however, isn't enough to reduce emissions. World demand for energy increased by 2.1% last year, and low-carbon sources could not keep pace. As a result, the word's energy-related carbon emissions rose by 1.7%, the first rise in four years. It's an important reminder that, despite all the talk about the growth of renewables, we still rely heavily on fossil fuels.

    But the capacity factor is low and the O&M cost is not free. The land required is not free. The capital cost is not free. The owners cost is not free. The cost of T&D is not free. Levelized cost means renewables still cannot compete with natural gas.

    You will be using fossil fuel your entire lives. Get over it.

    If you ignore the fact that solar has and will continue to double in efficiency / decreased price per watt / decreased price of installation over regular, repeatable time periods, you have a point.

    You don't need direct Sun light. Solar panels can generate around 80% of peak during dismal overcast days. And there are batteries. They really are not that expensive. Some places are even pairing batteries with fossil fuel like coal. A recent case study showed they were able to save $35mil in fuel over a 6 month period from a $55mil battery bank. Seems to me that batteries pay for themselves.
