The world just added a record amount of wind and solar in 2025, and it's not even close. New data from global energy think tank Ember shows that 814 gigawatts (GW) of new solar and wind capacity came online last year, up 17% from 2024's 696 GW.
Two tax credits, the investment tax credit (ITC) and the production tax credit (PTC), directly support investment in wind and solar electric power. In the Congressional Budget Office's baseline projections, those tax credits reduce federal revenues and increase federal spending.
This guide focuses on practical design steps for engineers: wind resource assessment, turbine and generator selection, electrical integration, grid codes, and project economics.
Using data from the National Renewable Energy Laboratory, we analyze the performance of wind turbines and photovoltaic systems, revealing distinct patterns in energy production and reliability.
Located at the crossroads of Europe and Asia, this facility combines 48 MW wind farms, 32 MW solar arrays, and a 60 MWh battery storage system, achieving 92% grid reliability in 2023 trials.
At first glance, wind turbines seem to rotate slowly-especially the massive wind blades. Yet, these low-speed giants can generate megawatts of power reliably. Why is that? The answer lies in aerodynamic design, mechanical engineering, and power system integration.
This study proposes a novel probabilistic power curve model for wind turbine and combines it with a hybrid wind farm model to quantify the accuracy and uncertainty of power prediction of wind farm over complex terrain with low computational cost.
Harness the combined power of sun and wind to slash your energy bills by up to 90% through modern hybrid renewable energy systems. Unlike standalone solar panels or wind turbines, these integrated solutions provide consistent power generation across day and night, sunny and cloudy.
Analysis of data from 2000-2024 reveals no statistically significant correlation between wind and solar generation growth and inflation-adjusted electricity prices, despite a 97-fold increase in renewable generation.
