On this week’s episode of #TruthtoPower, IntelStor's Founder & CEO, Philip Totaro continues a look into the future of the renewable energy market globally, looking at our power generation forecasts and the impact of public finance on renewable energy adoption rates.

All renewable energy sources combined generate over 10.7 petawatt hours of power as of the end of 2025. By 2030 that will be close to 13 petawatt hours per year, an increase of more than 22.5%.

In 2025, capacity factors have ranged from 11.26% for marine energy (ocean current and tidal), up to a global average of 54.56% for geothermal. Despite being inexpensive from a capital standpoint, solar PV only boasts a 14.87% capacity factor globally, and onshore wind saw a 24.23% capacity factor.

More than US$529 billion in public funding has been spent on the global power generation sector in the past 25 years. Of that, US$396.6 billion, or 75% has been spent on renewables. Solar PV, biogas and onshore wind are the most capital efficient renewable power sources. Meanwhile, concentrated solar, geothermal and solid biofuels are the least capital efficient renewable power sources.
