Rays of solar hope for Europe: A Midsummer reflection

For centuries, cultures in Europe have marked their calendars to celebrate Midsummer and the Summer Solstice. Traditionally a time to enjoy bright evenings, and the light and hope of the sun, the Summer Solstice falls on June 21. On the longest day of sunlight in 2022, Europe has much to hope for. After difficult pandemic years, enduring cost of living and energy price hikes, and the on-going, unprovoked, Russian war on Ukraine, Midsummer gives us a small moment to reflect on, and hope for, brighter times ahead.

As EVs drive off with Li-ion supply, the push to stationary storage alternatives accelerates

Lithium-ion storage: A much-needed development to support the rise of renewables in the coming decades

On Feb. 10 in Belfort, President Emanuel Macron announced his vision for the French global energy industry to 2050. He reaffirmed France’s desire to massively develop renewable energies as intermittent sources on top of the baseload provided by the nuclear industry whose revitalization has already made headlines since. Macron claimed they are “the only means to meet [our immediate energy needs] in a profitable and competitive way”. By 2050, the capacity of the French solar park should be multiplied by more than 10 to exceed 100GWp, while the onshore wind capacity could double to reach 37GW. Offshore wind power should also experience a real take-off as France aims to develop and build 40GW over the same period.
