Go Costa Rica! The Central American nation has been running on 100 percent renewable energy for 113 days and counting! The goal is a full year without fossil fuels and to be completely free from fossil fuels in just five years. 
Costa Rica has run on 100-percent renewable energy for the past 113 days, edging closer to its goal of being completely free from fossil fuels.

Looking at a list of dams removed in the US, it seems to me that most of them were not hydroelectric dams, and that most dams were removed because they were old and not economic and/or not safe. Then again, while many were old, small, inefficient and obsolete, it doesn’t help that sediment fills up behind the dams reducing their benefit and eventually causing a safety issue.

There appears to be no intent by the US to move away from hydropower.
http://energy.gov/eere/water/downloads/hydropower-memorandum-understanding
“The MOU established 13 overarching goals for sustainable hydropower generation and identified a specific set of activities that the Agencies collectively would undertake to elevate the goal of increased hydropower generation. These commitments were designed to represent a new approach to hydropower development that would result in clean, renewable power generation while avoiding or reducing environmental impacts.”

To me the big question about renewable energy is its profitability and for renewable to really prosper, it needs to be profitable for the companies to invest in.

From this point of view I wrote an article which you can find here: http://www.huntingvalue.com/renewable-energy-profitability

Comments are highly appreciated.
In this article I review how profitable the renewable energy market is in developing countries such as India and who are the beneficiaries in this market.

Car wiring isn't all that big for lighting/power applications?

If you used 12v solar panels from leisure shops, 12v leisure batteries and low load outlets for usb charging, you wouldn't need to do too much rectification.

Also for me it's 220-250v AC. Which uses smaller CSA cables still.

Michigan State University is poised to enter the exciting field of microbial waste management with an electrifying renewable energy twist. Researchers at the school have demonstrated that they can grow layers of electricity producing bacteria on films, deploying a scalable process that's this close to achieving commercial viability. So, in a world where you can grow

UK expert Matthew Lockwood has found a gem: once again, PV has grown faster than government officials thought possible, this time in the UK. After all the previous examples, one wonders when the doubters will realize how quickly wind and solar can grow. A guest post by Paul Gipe..

in the EU in general there is a high usage of renewables compared to the rest of the world so it's no surprise that in the UK almost a quarter of electricity comes from those sources also given the fact that the use of hydroelectric power is much lower (at 2% versus a EU average of 11.5%) so the EU might very well achieve independence from fossil fuels in, let's say, the next 40 years but the rest of the world is very much lagging behind at a mere 7% use of renewable sources for electricity with almost 65% of fossil fuels dependence.

|2 August 2016| Scotland A pioneering spin out company from the University of Strathclyde has secured a major funding boost which will enable it break into the renewable energy market. Synaptec is a leading developer of high performance fibre optic technology which reduces the downtime and operating costs of electrical power networks through improved monitoring. The £370,000 investment from the Equity Gap business angel syndicate, Sco...

Costa Rica celebrates 113 days of 100-percent renewable energy (and counting)

"With a 113-day stretch of 100-percent renewable energy under its belt and several months left in the year, Costa Rica is edging closer to its target. Costa Rica could be on track to match the record set with its renewable energy production last year, which accounted for 99 percent of the country’s electricity. That included 285 days powered completely by renewable sources, according to the Costa Rican Electricity Institute." | via Inhabitat #CostaRica #RenewableEnergy

+Carolyn Luce Of course you are correct, and this should have been obvious to me. I was in Costa Rica some time ago and went to one of their volcanoes and swam in the geothermally heated pools. Anyplace with an active volcano (I saw pyroclastic flows many times in just the few days I was at the volcano) is going to have readily available high temperature geothermal heat available.

add something like this to the ocean mills, perhaps have a chamber with a timed open and close water intake/release?

Yet another very old article from Eco Inventos. To rehash the issues with human power: Humans aren't capable of outputting much power, not nearly enough to power even the most efficient of homes or offices. Though exercise is a great thing for most people, people aren't very efficient at converting food to mechanical motion. A heat engine generator running on the same fuel as a person (biomatter) would produce many times as much energy. A solar panel for the same cost as this human powered generator would provide many times as much energy, and wouldn't use up food supplies.

The EU is the only region that can boast a core renewable share of 20% for Electricity consumption vs a world average of 7% although, when adding the half-renewable Hydroelectric source, both shares converge towards 25%~32% but the EU comes again on top when adding the last of the "clean" sources - Nuclear Fission - with a notable share of 60% vs a world average of 37%.
What would you like to say to the rest of the world in order to ensure that the remaining 63% of fossil fuels will definitely be replaced by 2070 ?
