Insight and inspiration in turbulent times.
In a sharing vision of a local renewable energy system, many households will generate their own renewable energy (as in solar photovoltaic or solar thermal systems on their rooftops), but many more, for whom this is not an option, will share in the ownership and operation of off-site renewable energy generation infrastructure such as wind turbines.
The staggering drop in the cost of clean energy has already upended the global power market over the past two decades — and that trend will only continue for the next two decades, according to new analysis from Bloomberg New Energy Finance (BNEF).
Transportation accounts for nearly a third of the country’s carbon emissions, of which 84 percent is attributed to cars and commercial trucks, the EPA reports. So, as Moyer sees it, it’s obvious that climate change and infrastructure should be tackled in tandem.
Unlike solar and wind energy, human power is always available, no matter the season or time of day. Unlike fossil fuels, human power can be a clean energy source, and its potential increases as the human population grows. In the Human Power Plant, Low-tech Magazine and artist Melle Smets investigate the feasibility of human energy production in the 21st century.
Falling costs allowed the world to add record new renewable capacity even as investment fell, according to a new report. The findings, from the UN Environment Programme (UNEP) and Bloomberg New Energy Finance (BNEF), show 139 gigawatts (GW) of renewable capacity was built in 2016.
The solar industry was responsible for creating one out of every 50 new jobs in the U.S. last year and the country’s fastest-growing occupation is wind turbine technician — so no matter one’s feelings on climate change, the renewable energy train has left the station, according to a new report.
Community energy refers to any kind of power plant using a renewable source of energy, that has been planned, financed and which is owned by a community of people (from the village to the house). And why would these energy communities matter?
A lively debate is ongoing on what should be the minimum energy return for energy invested (EROEI) in order to sustain a civilization. Clearly, one always wants the best returns for one’s investments.
I call upon all citizens in the renewables industries – leaders, employees, and investors alike – to articulate a clear vision of what a true Solar Civilization would look like. And then to fight for it hard in the year ahead.
The oceans of the world are a vast unexploited source of clean, reliable and predictable renewable energy. Could this energy help replace fossil fuels and be a solution to climate change?
It’s understandable that environmental organizations and activists would want to build public enthusiasm for renewable energy. But making wind and solar seem like they’re doing better than they really are could come back to bite proponents — and the climate.
No matter what any politician promises, coal-producing and coal-burning states would be wise to read the writing on the wall.
