By Kenneth Richard<\/a><\/em><\/p>\n\n\n\n

\u201cUnlike dispatchable fossil-fuel or nuclear generation, solar and wind power output varies unpredictably with weather conditions, leading to mismatches between supply and demand.\u201d<\/strong> \u2014 Sargentis et al., 2026<\/strong><\/h4>\n\n\n\n

New research<\/a><\/strong> utilizes stochastic analysis to assess the effectiveness of renewable energy sources (RES) in satisfying energy demands in Greece.<\/p>\n\n\n\n

Results indicate solar photovoltaic (PV) and wind power only meet annual energy demands 32% and 44% of the time, respectively. When electricity is needed to heat or cool a home, wind and solar power cannot deliver most of the time.<\/p>\n\n\n\n

Furthermore, a greater penetration of RES is known to \u201cincrease reliance on fossil-fuel generation or increases the risk of blackouts.\u201d<\/p>\n\n\n\n

Heavier reliance on wind and solar power is also \u201clinked to higher electricity prices.\u201d So we pay more to obtain less.<\/p>\n\n\n\n

\u201cAlthough solar photovoltaic (PV) generation can theoretically meet annual per-capita electricity demand, its stochastic variability significantly limits system reliability in the absence of storage. In the examined case study, a PV-only configuration satisfies demand during only about one-third of the examined time steps, while also producing substantial surplus energy that must be curtailed.\u201d<\/em><\/p>\n\n\n\n

If reliably meeting electricity demand is the intended goal of a higher penetration of wind and solar power, a documented ~62% combined failure rate demonstrate these technologies are severely unreliable and inadequate.<\/p>\n\n\n\n
