Portugal Produced More Renewable Energy Than It Needed Last Month

Last month, Portugal’s renewable energy sources provided more electricity than the country actually needed.

This rather astonishing statistic comes courtesy of Portugal’s national grid (REN) which revealed that in March the country’s wind, solar and hydroelectric plants accounted for 103% of electricity consumption, a figure unmatched in Portugal’s history.

Sadly there were some moments when fossil fuels had to take over to supplement the fact that renewable energy is not a reliably constant source of energy, but overall this compensated for by other periods when renewable energy over-produced.

What’s perhaps most impressive about this news however is that even at its minimum level, renewable energy was covering 86% of national demand and at its maximum it was providing 143% of national demand.

The vast majority of the electricity came from hydroelectric dams and wind which contributed 55% and 42% respectively.

While these months shouldn’t be considered the norm for Portugal just yet, the country’s renewable energy association (APREN) believes that by 2040 renewable energy can safely power the whole of mainland Portugal for the entire year.

Just 10 years after that Portugal has set itself the bold target of becoming completely carbon neutral.

Here in the UK the approach to renewable energy has been enthusiastic but not comprehensive. While Scotland enjoyed some record-breaking months in the last 12-months the country as a whole still suffers from a storage problem.

Because the UK’s weather is so inconsistent there are often times when the production by renewable energy doesn’t meet demand. As such that energy is either wasted or has to be stored.

While Scotland is trialling some experimental large-scale battery solutions, battery storage is still a costly business and to have even a hope of storing enough electricity for the UK we’re probably going to have to wait for more innovation.

The Eiffel Tower Installs Two Wind Turbines

The 126 year old Eiffel Tower is going green! A pair of camouflaged VisionAIR5 wind turbines were installed inside the scaffolding on the second floor, and are expected to generate 10,000 kilowatt hours of electricity every year. That’s enough to power the tower’s entire first floor; including history exhibits, a souvenir shop and restaurants. The […]

Dual Rotor Wind Turbine

Iowa State Aerospace Engineers Anupam Sharma and Hui Hu are exploring the possibility of adding a smaller, secondary rotor to wind turbines. The engineers studied the base of existing turbines and found two major problems. First, they are big round structural pieces that don’t harvest any wind energy because they are not shaped like an […]

Makani Energy Kite

Back in 2013 Google purchased a company called Makani, creators of the Energy Kite. Their goal is to make wind energy pricing competitive with fossil fuels, and they believe a new approach is needed. The Energy Kite is a new type of wind turbine, designed to generate more energy using 90% less materials. “Makani’s energy […]
