Here Comes the Sun! A Broad Constituency Emerges in the Battle for Solar. Solar energy is one of the brightest things going—a booming business sector spawning solid jobs, providing homeowners with local energy options, and saving the earth all at the same time. At least that’s what people thought. Early this year you couldn’t get … Continue reading Here Comes the Sun! A Broad Constituency Emerges in the Battle for Solar.
Wind and solar are growing at a stunning pace (just not enough to stop climate change) There’s good news and gloomy news on climate change in this new report on renewable energy from Bloomberg New Energy Finance. First, the celebratory stuff. Renewable energy — mostly wind and solar, plus a little geothermal and biomass — … Continue reading Wind and solar are growing at a stunning pace (just not enough to stop climate change)
Is the Electrical Grid Keeping Up with Smart Solar Inverters? Within the fast-growing solar-energy market, solar-inverter suppliers must keep pace with electronic technology advances in order to deliver more efficient and reliable parts at a lower cost. Inverter efficiency indicates the percentage of the available solar power that’s actually converted by the inverter and fed … Continue reading Is the Electrical Grid Keeping Up with Smart Solar Inverters?
GE wants to use CO2 pollution to make huge solar batteries Carbon captured by coal plants would drive turbines that deliver power at night. Two big problems have been vexing environmental scientists for decades: How to store solar energy for later use, and what to do with CO2 that’s been captured and sequestered from coal … Continue reading GE wants to use CO2 pollution to make huge solar batteries
Why The Energy Sector Is Being Disrupted Solar and wind energy has become so cheap that it is now competitive with coal and natural gas even without subsidies. In the US wind and solar has actually become so cheap with the 30% ITC subsidy that it accounted for the majority of new capacity additions in … Continue reading Why The Energy Sector Is Being Disrupted
Saving the sun: Battery manufacturer makes a play for disgruntled solar customers Even before the Public Utilities Commission of Nevada decided in February to stick with its plan to raise rates and service fees for rooftop-solar customers, those customers had begun to wonder whether the ability to store the excess electricity they generate would provide … Continue reading Saving the sun: Battery manufacturer makes a play for disgruntled solar customers
ERCOT: Wind, solar nearly two-thirds new capacity in 2016 ERCOT is rapidly building out its renewable energy, with solar and wind accounting for nearly two-thirds of new capacity. Even so, natural gas and coal still make up the majority of the system’s power mix. Natural gas generation capacity was at 59,507 MW by the end … Continue reading ERCOT: Wind, solar nearly two-thirds new capacity in 2016
JEA at odds with local solar power industry over value of electricity The value of electricity produced by rooftop photovoltaic panels versus the value of electricity generated and distributed by JEA is at the heart of a controversy being played out by the solar industry and the utility. Both the industry that sells and installs … Continue reading #JEA at odds with local solar power industry over value of electricity
Green Illusions – Why Wind and Solar Intermittency Matter For the first article in my Green Illusions series, “Why Wind and Solar Power Cannot Displace Coal” I focused on the normal swings in electric power demand over the course of a typical day and explained the differences between base-load power from coal and nuclear, peaking … Continue reading Green Illusions – Why Wind and Solar Intermittency Matter
Green Illusions Green Illusions – Why Wind and Solar Power Cannot Displace Coal We live in a crazy mixed-up world where half-truths abound as politicians, stock promoters, forecasters and advocates of all stripes blithely ignore the vulgar exigencies of objective truth when it comes to the energy supplies that make our industrialized economies and comfortable … Continue reading Green Illusions Green Illusions – Why Wind and Solar Power Cannot Displace Coal
