We have a renewable energy news category and comprehensive guide explaining exactly what renewables are.
Wave power or tidal power? The answer probably depends on where you are. If you have the frightening power that has always inspired names like Cape Wrath, then those tides should produce the most power in Europe. On the other hand, the regular movement of waves could well be capable of inspiring a design to accumulate energy over a lengthy period, albeit with less energy production per unit.
Uzbekistan stands out as a pioneer in developing renewables in Central Asia. Here is the ongoing story, as we look at how all nations try to live up to the promise of Paris COP21!

The race for solar power is on as fossil fuel investments are
divested and renewable technologies increase their percentages of many nations electricity production. The first major solar power project in every country is a real measure of progress. Uzbekistan stands out as having enormous amounts of solar potentials but with a current 89% usage of fossil fuels. To turn the tables on this energy budget would be a truly great achievement.
The regulation of unilateral decisions on hydroelectric power reminds all of us that the water around us really does not belong to us. It belongs just as much to the fish and the water cycle that supplies us with the precious stuff!
The future of our energy needs lies heavily with solar power. Unless wind and solar renewables kick off more and more new and technological moves, we will be left with failing and polluting energy solutions by politicians who understand even less about what could happen to the Earth than we do.
How should we progress to a world of renewable energy? Well the hydroelectric facilities we have are first-class while the wind and the tidal power industries are developing. Solar power represents to many people what photosynthesis means to the plant world-a cheap, reliable source of instant, if not yet storable, power.
We have ideas and giant international conferences coming up, on how to combat global warming and specifically what we can do with greenhouse gases. It could be, though, that some of the jokers in the pack are simply sequestering while Rome burns. After all, their employment depends on maintaining the coal, oil, gas and even fracking industries. Maybe replacing these industries with renewable energy technologies would use different engineers and spoil the party for many profitable companies?
The future for solar photovoltaic cells is bright. With wind and tidal power still developing, the efficient PV cells being developed seem sure to absorb more renewable sun-power than before and really push solar energy as a dominant form of energy. This league table will change a lot in the future but several countries are really setting out their store (and grabbing a part of the big market for cells.)
When we see countries developing a large renewable energy capacity, the whole earth can celebrate that there will be no more carbon emissions from some sources at least. Now for the riddance of fracking, coal and all gas and oil based industries, before the UNs latest warnings become tragically true even before we know it.
Wind and solar energy are beginning to take over in parts of Europe that are not importing low-cost fossil fuels. The green light is especially bright after a vote yesterday in the EU. This could light the way for vast technological improvement, and a healthy future.

The German situation is relevant to all of our future energy development, in utilising the energy that our renewables create. Efficient and creative storage solutions are emerging from new technology, but will any of the old storage capacity be useful, at least in the short-term?
While renewable energy struggles to make its mark on politicians, the easy way is to use the good old technology of getting fossils out of the ground and setting them alight. Has anybody remembered the globe is warming quickly now?
A research team in California has produced a system that can be used for artificial photosynthesis system as well as others. It seems likely that such a system will finally be able to produce the promised carbon neutral energy that we need in large quantities at low cost, in order to cool down the rapidly-warming planet.
The future of the planet depends on dropping fossil fuel. Are we in a position to make profits from the innovation needed for all those renewable energy technologies?
