What Changed In The Solar & Energy Storage Industries In 2018?

January 19th, 2019 | by Zachary Shahan

I started covering the solar energy industry seriously in 2009. It seemed like a hopping, exciting time in the industry — growth was exploding. I remember one early story in which readers admonished me a little because I put "Solar Power Exploding" in a headline, and they thought I was referring to genuine explosions. In 2019, 2009 and 2010 progress looks like anthills


Turning Solar Energy Into Liquid Fuel

January 6th, 2019 | by Nicolas Zart

Of all the strange things we do as a race on this planet, refining and over-complicating things are some of them. We're never satisfied with letting things be and often time favor extravagant conspiracy theories over reality. After all, how would the opposing piston engine and the convoluted internal combustion engine system have worked until now otherwise? Even though it has brought us this far, we need to get rid of inefficiency for more effective solar thermal energy storage systems


What Changed In The Solar Energy Industry In September & October?

November 29th, 2018 | by Zachary Shahan

It has been a while since I wrote a "What Changed In The Solar Energy Industry ... ?" article, so I'm lumping two months of news together for this one as November closes. That means cutting out more of the "small" stories, which should make this an especially potent roundup of notable changes in the electric vehicle industry. Enjoy!


New Mexico Elects Potential Climate Hawk As Governor

November 8th, 2018 | by Kurt Lowder

New Mexico has elected US Congresswoman Michelle Lujan Grisham to become its new governor by an impressive 14 point margin. The previous governor, Susan Martinez, was a climate change denier (she was not up for re-election). In her Clean Power, Clean Future plan, Grisham stated: "Inaction by the Martinez Administration has left us falling behind other states in pursuing renewable energy and clean tech industries."


$1B Palen Solar Project Gains Fed Approval for 500 MW PV, Side-Steps California Energy Commission

November 2nd, 2018 | by Charles W. Thurston

The decade-old 500 MW Palen Solar Project has finally won decisive federal approval to go ahead as an estimated $1 billion photovoltaic project in the California desert after years of controversy and varied ownership. The November 1 approval by the US Bureau of Land Management also side-steps years of regulatory consideration of the project by the California Energy Commission, when the plant was still being proposed as a solar thermal project.


Shell New Energies VP: “We Are Further Along Than People Realize”

July 10th, 2018 | by Guest Contributor

With a string of new investments and acquisitions in the past year (you can find a unique overview further on in this article!), Shell has quietly stepped up the pace of its transition from an oil and gas company into an energy company. “We are further along than people realize”, says Mark Gainsborough, Executive Vice-President of Shell New Energies, in an exclusive interview with Energy Post. According to Gainsborough, there is a “shift in thinking” within the company that is now irreversible. “People in Shell see a lot riding on the success of New Energies. And we are considered one of the most attractive units to work in. Anyone under the age of 35 wants to work for New Energies.”


US DOE Funds Projects Aimed At Cutting Costs Of Solar Thermal Desalination

July 8th, 2018 | by Nexus Media

Desalination plants require a tremendous amount of energy, making them extremely costly to run. And, if that energy comes from burning fossil fuels, it will only make climate change worse. The Department of Energy (DOE) is looking to tackle both problems by funding research aimed at dramatically reducing the cost of using solar power to get the salt out of seawater


New US Solar Record — 2.155 Cents Per kWh! (with Escalator for Inflation)

June 14th, 2018 | by Kurt Lowder

We have seen solar power in the Middle East come into the low 2 cents per kilowatt-hour (kWh) range. We have seen it under 2 cents per kWh in Mexico. Misguided, casual observers claimed these prices only occurred due to heavily exploited labor, but now we have also seen 2.155 cents per kWh in the United States. This contract was one of six contracts that Nevada Power recently signed. All six contracts came in under 3 cents per kWh


What Changed In The Solar Energy Industry In May?

June 12th, 2018 | by Zachary Shahan

Following up on our "What Changed In The Electric Vehicle Industry In May?" roundup, below is a summary of major solar energy and energy storage news from May. This roundup isn't just about big project announcements. The point is to highlight notable shifts or milestones here or there in the industry


Solar Ponds — Large Passive Solar Heat Collectors Relying On Brines (Used To Generate Electricity)

April 29th, 2018 | by James Ayre

Solar ponds are a type of passive solar energy technology whereby pools of saltwater are used to collect and store solar thermal energy — making use of the natural formation of a salinity gradient in such bodies of water, whereby heat isn't easily transferred between a high-salinity layer at the bottom of the body of water in question and a low-salinity layer on top


Solar Walls, Trombe Walls, & Passive Solar Heating 101

April 28th, 2018 | by James Ayre

Solar walls, glazed solar collectors, and so-called Trombe walls are all different types of passive solar heating technologies based around the use of materials meant to absorb solar radiation (generally, dark-colored materials since dark colors absorb the heat better) and thermal mass. The end goal is to provide space heating, and often ventilation as well


Munro Academy Teaches Students About Renewables With Hands-On Projects

April 28th, 2018 | by Kyle Field

One of the challenges posed to students was focused on climate change. What can be done at the school to reduce its carbon footprint and more than that, to impact Cape Breton Island in a positive way? The students were filled with ideas and opened up the floodgates to their teachers.  Out of the long list and through a process of discussion, several ideas rose to the top and were selected as the focus on action for the project.


Solar Technologies Of Days Gone By — Solar Thermal Trains, Solar-Powered Ice Cream Makers, & Solar Steam Engines

April 22nd, 2018 | by James Ayre

Solar energy has been exploited in direct capacities, for various purposes, well before solar photovoltaic cell and module technology became the most prominent example of "solar energy technology." Solar stills, solar cookers, sunlight concentrators, solar furnaces, solar fire starters, et cetera, have a long history of use and/or suggestion of use. For instance, there's fairly good evidence (though disputed by some academics) that solar fire-starters have been in use in Central Asia for a fair many thousands of years
