Hybrids don’t do as well in winter for reasons ranging from modified winter gasoline formulations, to increased stationary warm-up time, to increased heater usage, to reduced battery performance in cold weather. A recent report in MIT Technology Review claims that the situation gets even worse when moving from hybrids to all-electrics. But before we snow on the EV parade, let’s ask how serious these cold weather drawbacks actually are.

Based in San Francisco, Greenlots is global provider of open-standard technology solutions for electric vehicle networks — allowing for automated demand response between the utilities and the charging infrastructure.
Innovations in energy efficiency project financing are now offering guaranteed lower electricity bills to the commercial real estate sector.
Heat recovery ventilation systems are an energy efficient solution in extremely cold climates, and they’re growing in popularity around the world.
The displaced polar vortex, with its frigid temperatures and strong winds, has caused energy use to soar–creating supply shortages and rising energy costs. But wind power has performed well overall.
Cisco has been working in the smart cities space for seven years now — providing services including traffic management, parking assistance, waste management, pollution reduction, virtualized learning, security and health care.
This week they took another major step, announcing a strategic partnership with AGT International — a solutions provider that works specifically in the smart cities space, where they have fielded an impressive array of solutions ranging from law enforcement, to environmental monitoring to citizen services.
Fossil fuels have long held an advantage over renewables in that they provide a combined energy source and storage medium in one substance, be it gasoline, coal, oil or natural gas. The fact that you can save it, store it, then use it continuously whenever you need it is a tremendous convenience.
That gap is now being reduced with the advent of combined solar-storage systems. These new systems not only match the capability of fossil fuels, but can actually go them one better. How?
An Atlanta park with a lake that enhances urban water management and city living, a highly energy efficient mixed-income, mixed use housing development in Sacramento powered by solar energy, and a riverside park in Iowa that mimics nature in enhancing the quality of residents’ lives while reducing flood risk are among the winners of this year’s EPA Smart Growth Achievement Awards.
Popular ridesharing companies like Uber, Lyft and Sidecar have long-operated in a legal gray zone. While the California Public Utilities Commission’s (CPUC) unanimous approval of new regulations around ridesharing services last September helped to clear some of the ambiguity, scores of questions remain. Chief of these are liability issues — just who is to blame when things go wrong with ridesharing?
Guaranteed lower energy bills, increased occupant productivity and reduced emissions are the promise of the transformative “hybrid electric building.”
Flip through this photo essay, featuring images snapped on a recent tour of the city during Abu Dhabi Sustainability Week 2014, for an up-close look at some of Masdar City’s most impressive sustainable design elements.
The boom in solar energy in the U.S. is due in large part to innovative financing, putting solar within reach of almost any business or homeowner with a roof, for little more than their signature. But for nonprofits it’s a different story.
Solar power is a great source of energy: It’s both infinite and eco-friendly. However, some people may need a little extra incentive to have solar panels installed on their roofs. Israeli startup Generaytor is all about showing people the financial possibilities of going solar.
It is normally assumed that the larger the audience the more impact you can have. For the past 20 years Denis Hayes has relied on a different approach.
