When a city decides to transition from fossil fuels to clean energy, headlines follow. But the work has only just begun. Cities have many options for generating and purchasing renewable electricity, each of which comes with distinct benefits and challenges.

Hawaii has a new, game-changing tool in its renewable energy arsenal. Power producer AES Corporation and the not-for-profit Kaua'i island Utility Cooperative (KIUC) unveiled what's claimed to be the world's largest solar-plus-storage peaker on the island of Kauai on Tuesday, the Lāwa'i Solar and Energy Storage Project.
This is a significant step to help the Aloha State reach its 100 percent renewable energy goal by 2045, one of the most aggressive decarbonization targets in the nation.

This year's Living Planet Report shows that populations of animals—including mammals, birds, fish, reptiles and amphibians—plummeted by 60 percent between 1970 and 2014. But those living in freshwater are experiencing a far more drastic decline: 83% since 1970. It's a sobering statistic and one tied directly to the ever-increasing pressures that people are putting on natural habitats.

The most recent international report on climate change paints a picture of disruption to society unless there are drastic and rapid cuts in greenhouse gas emissions.
Although it's early days, some cities and municipalities are starting to recognize that past conditions can no longer serve as reasonable proxies for the future.

It seems like every few months there's a new cellphone, laptop or tablet that is so exciting people line up around the block to get their hands on it. While the perpetual introduction of new, slightly more advanced electronics has made businesses like Apple hugely successful, the short shelf life of these electronics is bad for the environment.
As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.
To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.
Once finished, the 70-megawatt system will be the largest in the world by far; the current record-holder is the comparatively shrimpy 11.5-megawatt array in India that can power 8,000 homes.

Did you make it through Donald Trump's State of the Union address? If you did, congratulations on your endurance. Not everyone can handle sitting through more than an hour of lies, deceit and distortions. Then again, we've all been surviving and fighting through the past 12 months of this administration. Resistance takes stamina, and it's clear that it's made us stronger.

Let's talk for a moment about how the climate movement is going to fight back in 2018.
But first, a public service announcement.
This Jan. 31, movement leaders like the one-and-only Bernie Sanders, 350.org co-founder Bill McKibben, Rev. Lennox Yearwood of the Hip Hop Caucus, Jacqueline Patterson of the NAACP, and more, are coming together for an event called "Fossil Free Fast: The Climate Resistance," to lay out a movement game plan for 2018.
If we want to accelerate the world's renewable energy transition, we'll have to modernize the electric grid and we'll need much better batteries. Just look at Germany, which generates so much clean energy on particularly windy and sunny days that electricity prices are often negative.
Sure this is good news for a German person's wallet, but as the New York Times noted, "Germany's power grid, like most others around the world, has not yet adapted to the increasing amounts of renewable energy being produced."
