Here is an account of something I stumbled upon on a visit to Munich last year which I hope will be of interest. The four laws without which nothing whatsoever throughout the universe that happens, happens.
According to the US Geological Survey, 66% of public water comes from surface water. Presumably some of that is pumped at some point, but even if only half of that were gravity fed, the potential for electricity production from municipal water pipes is significant.
Deterministic weather forecasts have their place, but probabilistic forecasts are the clear choice for alternative energy companies that take the weather seriously and need long-term data.
And while lithium has traditionally been controlled by a handful of major global suppliers, spiking demand is changing this landscape drastically.
Universal access to renewably-generated electricity could be within the foreseeable future, with cleaner air and water as the side effects. Better public transportation systems will make life more enjoyable for commuters all over the country, as will a self-sustaining energy economy.
Sam Grobart for Bloomberg: There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there. Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea. A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current. Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly.

Solar Energy Index Underperforms S&P in Q1 2016
In 2015, the ethanol share of gasoline was 9.9%, and the biodiesel share of distillate was 2.4%.
In September 2015 SunGift Energy completed the UK's first 'solar carports' on the top decks of two multi-storey car parks.
Status report shows that RPS policies likely to remain an important driver for renewables growth.
We asked one customer to model cost savings for us. Note that we didn't pay for this, and it was based on a real bid made in 2015.
CPH Post: Researchers at the University of Copenhagen have discovered a natural process they are calling ‘reverse photosynthesis’. They have observed how the energy in solar rays breaks down rather than builds up plant material, as happens in photosynthesis. Sunlight is collected by chlorophyll, and when combined with a specific enzyme the energy breaks down plant biomass. The resulting product can then be used as a biofuel. By increasing production speed while reducing pollution, the discovery has the potential to revolutionise industrial production. “This is a game-changer, one that could transform the industrial production of fuels and chemicals, thus serving to reduce pollution significantly,” said Claus Felby, the University of Copenhagen professor who headed up the research. “It has always been right under our noses,” he said. “Photosynthesis by way of the sun doesn’t just allow things to grow – the same principles can be applied to break plant matter down, so that the immense energy in solar light can be used so that processes can take place without additional energy inputs.” Cont'd...
Panasonic HIT® panels recently set a world record for conversion efficiency at the research level (laboratory), a full percentage point increase over the previous record.
The desire to halt climate change has drawn researchers around the world to the pursuit of CO2 conversion.
Newly Built Concentrated Solar Power Plants - Time To Consider Flushing and Cleaning as an Industry Standard?
A recent research paper published in Applied Thermal Engineering highlights the importance of defined protocols to effectively flush and clean newly built facilities, which is needed prior to filling the system with expensive fluids, such as solar thermal fluids.
