    Growing demand requires growing supply. With more and more data centers and industrial facilities coming online, the United States will likely need 40 GW of incremental peak power generation – requiring hundreds of billions of dollars of related investment – just over the next few years. As large corporate buyers of power seek to meet their climate goals, they are increasingly looking at nuclear power as a scalable and cost-effecti...

    With rising investor demand and regulatory pressure in certain jurisdictions, company disclosure of their exposure to climate risks and their environmental impact has emerged as an expectation with tangible economic benefits. Increasingly, companies can improve their access to lower-cost capital by disclosing their exposure to climate risks and opportunities. Indeed currently over 23,000 companies now report through CDP, underscori...

    Critical minerals are absolutely vital for the energy transition. Without nickel, copper, lithium, cobalt and other rare earth elements, we simply cannot produce the solar modules, wind turbines, batteries and other technologies necessary to decarbonize the global economy. It’s no surprise then that demand for these critical minerals is expected to almost triple by 2030. 

     

    But mining, processing and incorporating these critical mine...

    For the world to meet its growing need for low-cost clean energy and achieve ambitious decarbonization targets, land-based onshore wind energy must be an increasingly large part of the electricity generation mix—potentially as much as 20-41% by 2050, according to BloombergNEF and the International Energy Agency (IEA). But there is a challenge: the most efficient and cost-effective wind turbines, currently applied only in offshore w...

    The maritime industry transports over 80% of goods worldwide and is essential to the deployment of climate technologies.  At present, the industry contributes approximately 2 to 3% of global emissions, but this figure is projected to grow without major changes to the industry and its ancillary services. However, decarbonizing the maritime industry is unusually challenging.  As the president of Marine and executive vice president at...

    As the accelerating deployment of variable wind and solar resources pushes us ever closer to Net Zero – or the state whereby we’re not emitting any more greenhouse gas emissions into the atmosphere than we are simultaneously removing – we increasingly need to deploy both battery storage as well as dispatchable renewable baseload generation. But despite its ability to serve as dispatchable renewable baseload, geothermal energy today...
