DTE's green bonds will help pay for solar and wind investments

True enough, green bonds are nothing new.  Created to fund projects with environmental or climatic benefits, the first green bonds were issued in May 2007 by the European Investment Bank (EIB).  The...

Billionaire Bailouts v. Biofuels

Trump in a pickle: support his beleaguered EPA Administrator over oil refinery bailouts, or rally his Midwestern farm-state base? In Washington, Senator Chuck Grassley of Iowa tweeted: “I’ve supported Pruitt but if he pushes changes to RFS that permanently cut ethanol by billions of gallons he will have broken Trump promise & he should step down & let someone else do the job of implementing Trump agenda if he refuses.” Grassley explicitly called on Pruitt to back a key campaign pledge from 2016 that helped unlock farm state support and propel Trump into the White House. 1/19/16 Trump at IA Renewable fuels summit: EPA...

Ten Clean Energy Stocks For 2018: Oddballs Spring Back

After a stormy winter for the broad market and clean energy stocks, including my picks, March and April brought relative calm.  Better yet, my model portfolio has rebounded from its February lows, although its benchmarks (SDY for the broad market of income stocks and YLCO for clean energy income stocks) have mostly been treading water. The gains were led by two of my less conventional clean energy picks, Seaspan (SSW) and InfraREIT (HIFR).  Seaspan owns (mostly very efficient) container-ships, which most people would not associate with clean energy, but which I include because they they are much less energy intensive...
