New wind and solar generation costs fall below existing coal plants – FT

New wind and solar generation costs fall below existing coal plants – FT

Estimates jeopardise Trump’s hopes of reviving mining industry in US Source: Financial Times This news reminds me of an old post that reported the progressive decrease of wind and solar costs. Apparently these two technologies have now reached coal, i.e. the benchmark technology, at least “in many areas of the US”, as stated in the article. Now the tendency must be consolidated, of course, but it is normally stressed that renewables will really take off only when they become cheaper…

New Asian coal plants knock climate goals off course – FT

New Asian coal plants knock climate goals off course – FT

Growing ‘disconnect’ between energy markets and emission targets Source: Financial Times Whereas old-technology and high-emissions coal-fired power plants have progressively been approaching the end of their operational life in Western countries, in Asia (notably China and India) such plants are averagely much more recent, and many are under construction. This will result in a lock-in of carbon dioxide emissions for decades, with detrimental effects on climate change mitigation. This is one of the biggest issues regarding  the energy sector in…

Renewables 2018 – IEA

Explore key findings from the IEA’s market report on renewable energy Source: Renewables 2018: Key Findings The International Energy Agency has recently published the “Renewables 2018” report, which discusses both the market status and the forecast from 2018 to 2023. The report is not for free, but the relevant webpage provides plenty of information, both as an overview and sorted by sectors (power, heat, and transport). The executive summary can also be downloaded. It is practically impossible to summarize the…

IRENA points to offshore energy benefits for economies at G7 – IRENA

Speaking at the Oceans Partnership Summit during G7, IRENA Director-General Adnan Z. Amin underlined the potential of offshore renewable energy to meet energy demand, stimulate economic growth and generate employment – hallmarks of the global energy transformation. Source: IRENA points to offshore energy benefits for economies at G7 Offshore wind in the spotlight: is this technology going to be a game changer in the power generation sector in the next decades? For sure, so far renewable development has mostly focused…

Off-grid Renewables are Growing, Bringing Socio-economic Benefits to Millions – IRENA

Off-grid Renewables are Growing, Bringing Socio-economic Benefits to Millions – IRENA

New IRENA brief highlights positive momentum for off-grid renewable energy, and its transformative impact as a key pillar of Sustainable Development Goal 7 Source: Off-grid Renewables are Growing, Bringing Socio-economic Benefits to Millions I had missed this interesting brief published by IRENA about one month ago! As discussed in many posts, one of the main topics within the MERCURY project is the analysis of the issues related to the penetration of variable renewable energies in the electricity grid. For this…

Green energy is gold for California, US – SF Chronicle

Green energy is gold for California, US – SF Chronicle

I am a physicist, and an energy and sustainability science researcher, and I live in California because of its penchant for not just setting but actually achieving big goals and adopting bold visions others may consider too ambitious. What California proposes, we research, debate and then accomplish. In fact, we often exceed the goals skeptics have deemed unmeetable. This is why I believe that California should — and ultimately will — pass into law the “100 Percent Clean Energy Act”…

Is reliable energy storage on the horizon? – FORBES

Is reliable energy storage on the horizon? – FORBES

Green and renewable energy markets are bringing power to millions with virtually no adverse environmental impacts, but before we can count on renewables for widespread reliability, one critical innovation must arrive: storage. Source: Is reliable energy storage on the horizon? In my previous posts I talked several times about storage, grid, system integration of variable renewable energies, and so on. However, I never shared non-technical articles where these issues are discussed in an accessible way for non-experts: I decided to…

World Energy Investment 2018: Key Findings – IEA

2017 was the third consecutive year of decline in global energy investment Source: World Energy Investment 2018: Key Findings The International Energy Agency (IEA) regularly releases very interesting reports on the global energy landscape. A new document was produced in the past days, this time focusing on energy investment. News is not good, actually. The following statement by Fatih Birol, IEA Executive Director, clearly summarizes the main outcome of the report: “The decline in global investment for renewables and energy…

The gas industry’s future looks bright over next five years – IEA

The gas industry’s future looks bright over next five years – IEA

Latest five-year market forecast highlights deep transformations in natural gas markets Source: The gas industry’s future looks bright over next five years, according to IEA analysis Natural gas is notoriously the least CO2-emitting fuel among fossil fuels. For this reason, in the medium run it will likely drive the transition phase of the decarbonization of the energy system. It is more difficult to make a forecast for the long run, instead: models in fact show conflicting results because if it…
