Why is green energy infrastructure booming despite global economic woes?

The Covid-19 pandemic and resulting economic fallout have had a variety of impacts on the clean energy transition, with some sectors being more affected than others. Earlier this year, the International Energy Agency (IEA) warned of slowed progress towards sustainable energy goals due to Covid-19 and reversed progress in many areas crucial in reaching net zero, such as energy efficiency, clean cooking, or access to electricity. There is one sector, however, that has shown remarkable resilience since the beginning of the pandemic and has been able to maintain, and even accelerate, its rapid growth since 2020: green energy infrastructure.

Europe can compete effectively with Asian solar manufacturers with innovative long-term PV technology solutions

The world’s energy sector is concentrated in solar, wind, electricity transmission/distribution and hydroelectric power. For example, investment in solar power plants alone is higher than investment in natural gas, coal-fired and nuclear power plants combined. This is encouraging, but another fact is worrying: China’s exports of solar modules to Europe in the first four months of 2022 were 2.5 times higher compared to 2021. In April alone, nearly 8 GW of solar modules worth more than €2 billion were imported from China into Europe.

Uzbekistan is steaming ahead in the race to carbon neutrality

The war in Ukraine continues to disrupt the global energy sector and, combined with the recent heatwaves affecting Europe, the need to restructure economies is starker than ever. Luckily, there are some countries that have kept working on their energy transition reforms and taking tangible actions towards tackling climate change. Uzbekistan is one of them.

Considerations for solar projects during heat waves

High temperatures can affect different components of PV systems. Inverters can fail, the efficiency of solar modules can decline, and existing cell damage can become worse. However, investors, planners, and operators can adjust to heat waves in a number of different ways.

Italy publishes new national guidelines for agrovoltaic plants

On June 27, the Guidelines for The Design, Construction and Operation of Agrovoltaic Plants were published in Italy by the Ministry of Ecological Transition, in coordination with the Council for Agricultural Research and Analysis of Agricultural Economics (CREA), Gestore dei Servizi Energetici S.p.A. (GSE), the National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA), and Research on the Energy System S.p.A. (RSE). From now on, developers and, in general, RES plant owners will have to consider the principles herein outlined, to have their plants classified as agrovoltaic.

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.

Polysilicon growth lags behind demand

Policy developments worldwide have led to strong growth of renewable energy. Demand from large markets such as Europe, China, and Brazil continues to beat expectations. InfoLink has revised up its module demand forecast to 239-270 GW this year – representing significant growth of up to 34% from last year’s 178 GW of installations. However, analyst Dora Zhao finds that availability of polysilicon could be a major limiting factor in meeting this demand.

At home on the sea: Marine PV and boats

In 2018, Lyall Burgess and wife Katie started a business called Sun Powered Yachts. The original idea came to them in Tahiti, where the couple had chartered a yacht to explore the French Polynesian island. As Lyall Burgess tells the story, “We were on a charter boat in Tahiti and we were having to run the engine four hours a day to keep up with the fans and the refrigeration. And you’re in this beautiful anchorage, sunshine all day, and have to listen to this engine because the yacht didn’t have any solar panels. So, it kind of all happened at the same time. We found out about these panels, the opportunity was there, we just went for it and created Sun Powered Yachts … and it’s grown ever since.”
