On this week’s episode of #TruthtoPower, IntelStor's Founder & CEO, Philip Totaro discusses how the commercial implementation of new solar technology will unlock a repowering and efficiency revolution that could double the amount of solar used on the grid.

Efficiency improvements in solar cells are being introduced all the time by various research entities and industry companies who have invested heavily in developing technologies with more robust performance. The latest approach is a perovskite-based cell. That is a calcium titanium oxide mineral which researches have been investigating for use in solar cells since the early 2010’s.

China’s LONGi has seen efficiencies of between 34 – 35% more recently as they continue to develop 2-terminal monolithic perovskite based cells.

With the bulk of the global solar capacity having been installed in the past 15 years, there will be a time within the next 5 – 10 years when solar PV asset repowering will need to be undertaken. Solar asset repowering should cost less than half that wind energy asset repowering, at approximately US$175,000 / MW versus US$425,000 / MW respectively.

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.

On this week’s episode of #TruthtoPower, IntelStor's Founder & CEO, Philip Totaro kicks off a new series with a deep dive into the future of the renewable energy market globally, with the launch of our latest global market forecast.

The most important outcome is that renewable energy is now 50% of the power generation mix. Capacity additions across all renewable energy technologies now total 4.89TW globally with solar PV leading the way, followed by hydropower then onshore wind.

The world went from 25% renewables as part of the power generation mix in 2000 to just over 50% in only 25 years. IntelStor is also able to forecast that based on a 2 – 3% growth rate for renewable energy vs non-renewables, the world will eliminate fossil fuels before 2050 and could even eliminate dependence on nuclear technology for power generation as well.

Solar PV leads the world with more than 2 TW installed globally as of the end of 2025. Onshore wind will overtake hydropower as the second largest renewable power generation source by capacity installed in 2026.
