Overview and key findings – World Energy Investment 2023 – Analysis
Investment in new coal-fired power plants remains on a declining trend, but a warning sign came in 2022 with 40 GW of new coal plants being approved – the highest figure since 2016. Almost all of these were in China, reflecting the high political priority attached to energy security after severe electricity market strains in 2021 and 2022, even as China …
Australia: Large-scale battery storage investments break billion-dollar barrier in Q2
Image: Powin Energy. More than AU$1 billion (US$0.65 billion) of financial commitments to large-scale battery energy storage system (BESS) projects were made in Australia in the second quarter of this year. If hybrid …
Power sector – World Energy Investment 2019 – Analysis
Global power sector investment dipped by 1% to just over USD 775 billion in 2018, with lower capital spending on generation. Investment in electricity networks edged down, although investment in battery storage surged by 45% from a relatively low base. Investment in coal-fired power declined by nearly 3% to its lowest level since 2004, …
Positive outlook for battery energy storage investment
As the UK rapidly shifts from fossil fuels to renewable power – bringing greater volatility to energy markets - it''s no surprise that Bloomberg has hailed the 2020s as'' the decade of energy storage''. In its 2021 Global Energy Storage Outlook, BloombergNEF (BNEF) forecasts that this decade will see a twenty-fold global expansion in non-EV battery …
Energy intensities, EROIs (energy returned on invested), and energy payback times of electricity generating power plants …
For fossil fuels the process chain ends when the fuel is delivered to the power plant, completely disregarding the power plant itself and therefore reducing the energy demand remarkably. Again, the energy output for fossil fuels as well as for "renewables" has been weighted by 2–3, but for nuclear energy no weighting was …
