Clearstream believes that decarbonization of the energy industry will continue and accelerate, driving consistent and repeatable opportunities for middle-market investment throughout the energy transition period:

Decreasing Cost of Renewable EnergyThe cost of renewable energy has fallen dramatically over the past decade, making these resources more cost-competitive with traditional fossil fuels.

Growing Demand for SustainabilityConsumers are increasingly demanding sustainable energy and products, and corporate behavior is quickly following.

Continued Regulatory TailwindsDecarbonization is at the political forefront globally, driving favorable regulation, government grants and financial incentives to support energy transition.

Large and Growing Addressable MarketA significant increase in future clean energy investment will be needed to achieve climate goals laid out by The Paris Agreement.

Favorable Competitive LandscapeAvoid competition for energy transition investments by targeting the underserved middle-market sector.
