We have been tracking developments in renewable-energy technologies since June 2003 and have published over 250 articles on the theme during the last 18 years.

Each of the technologies—whether it is wind power, solar photovoltaic, hydrogen, geothermal, ocean or tidal power—have important roles to play in the global-energy transition.  The COVID-19 pandemic also accelerated the energy transition with more nations prioritizing a greener economic recovery.

We believe that broad adoption of clean energy remains in the early innings.  Clean energy and its storage are transformative technologies that bring productivity gains and cost savings, which translate into massive investment opportunities.  To leverage our conviction in the sector, we created the 13D Clean Energy Portfolio IndexSince its inception in October 2018, the index has generated a total return of 473.6%, versus 71.5% for the S&P 500 Index and 63.0% for the MSCI World Index.*
