Reuniwatt, member of the International Energy Agency’s Task 46

In order to get the best out of solar energy, a good knowledge of the resource is essential. An accurate assessment of the solar resource is important for dimensioning solar plants – whether they are thermal, photovoltaic or concentration –. Reliable and trustworthy production forecasts during a plant’s operating phase are just as important. TSOs need them to properly handle the variable availability of the

On the cusp of COP21: Innovation and renewables, figureheads of December’s negotiations

From November 30th to December 11th, France will host the 21st Conference of Parties (COP21).

Reuniwatt to provide short term forecasts for the IssyGrid® demonstration project alongside Total

Expert in Photovoltaic (PV) energy production forecasting, Reuniwatt signed up a partnership with Total. Reuniwatt will thus provide solar power production forecasts for the IssyGrid® demonstration project. Prior to the agreement, the forecasts were provided every 6 hours ahead and for the day to come. Reuniwatt introduces shortcasting. PV production forecasting: a determining stake for smart grids One of the main challenges of smart-grids is

Musk unveils Tesla’s Powerwall: En route to a new energy era?

Last April in Hawthorne (California), founder of Tesla Motors Elon Musk, the current leader in the electric vehicles sector, made an entrance in a spectacular fashion during his brand new home batteries’ debut conference. Tesla wants to revolutionize the energy sector but can it really be done? A cheering and overall overexcited crowd greets Elon Musk as he enters the stage. With a curt nod

Solar impulse: the solar airplane

If you live in Abu Dhabi, Muscat or Ahmedabad, you might have seen a weird bird flying above you. Wider than a Boeing 747 but weighing only 1% of its weight, Solar Impulse is a 4-engine solar-powered plane on its way to fly around the globe. It has absolutely no other fuel than solar energy. Flying only thanks to solar energy would have seemed impossible

Decoupling the economy and carbon emissions?

Good news! The International Energy Agency (IEA) just released a note stating that carbon dioxide emissions related to energy did not increase in 2014. There is usually a strong correlation between global economic growth and carbon emissions: as the economy is growing, people are using more energy to fuel this growth and more people get access to energy in emerging countries. Even when the economy
