Imagine a world where the concept of “waste” does not exist. A world in which nothing gets discarded, every industrial product gets reassembled into something useful, each unit of energy is offset and anything and everything is a renewable resource. This is the design principle and environmental philosophy of “zero waste”.
It is a rough time to be a startup in the Solar Photovoltaic sector. The financial crisis and deep recession has not only dried up capital, but has also hit demand for solar panels, which has lead to a global supply glut and a price collapse. In this very difficult environment startups must compete with much larger established global suppliers that have factories of hundreds of megawatts each, an established customer base and well developed brand names and sales channels. In this post we look at five promising CIGS thin film Solar PV startups based in the US and try to catalog their unique strengths and accomplishments.
In this survey we are looking at the large US headquartered solar PV manufacturers with a view to examine how they are doing in this difficult economic climate. As basically anyone knows, who has not been cloistered away meditating in some cave, 2009 has been a very tough year for pretty much everyone.
California’s biggest utility PG&E is seeking approval from state regulators for a power purchase agreement with Solaren Corp., a Southern California company that has contracted to deliver 200 megawatts of clean, renewable power over a 15 year period, beginning in 2016. Power from out of this world, that is. Solaren says it plans to generate the power using solar panels in earth orbit, then convert it to radio frequency energy for transmission to a receiving station in Fresno County. From there, the energy will be converted to electricity and fed into PG&E’s power grid. UPDATE: The California Public Utilities Commission gave its approval yesterday to the project giving it the green light to proceed.
It’s no secret that air travel is hard on the environment; but it’s also one of the key ingredients to a robust global economy. The World Intellectual Property Organization says that air travel accounts for 35 percent of goods traded internationally (by value) and over 40 percent of international tourism. On the upside, aviation generates 5.5 million jobs and contributes over $400 billion to global GDP. On the downside, aviation also accounts for roughly 13 percent of global transport emissions and 2 percent of global carbon dioxide emissions.
By some measures 2009 has been the worst year in the young solar PV sectors history. In fact, global revenue for Photovoltaic (PV) panels is expected to drop by nearly 20 percent in 2009, as oversupply causes prices to crash by nearly fifty percent. Many of the weaker firms may not survive this shakeout and right now things do look very gloomy – even though by some other measures 2009 is not as bad as it may seem. For example more newly installed capacity (4.2 GW) is installed this year than any year – ever; however this is of little comfort to the many firms in this sector that are being buried under an avalanche of negative revenue. This article examines the short term outlook for the solar PV sector going forward, basing itself on market data from a recent iSuppli study.
Distributed energy systems can range from the micro sized do it yourself systems being installed on rooftops and on hilltops to small scale systems ranging up to around 20MW (megawatts) of capacity, although it must be understood that this is a pretty fuzzy boundary. The defining characteristic of distributed energy systems is that they generate energy close to the point of use where that energy will be consumed; hence the admittedly fuzzy 20MW upper boundary for their size.
The sun can help coal fired power plants burn less coal by pre-heating the water used to make high pressure high temperature steam during periods when the sun is shining. In other words the sun would do part of the work of producing high pressure/ high temperature steam and in this manner the overall hybrid solar/coal power plant would use less coal than a coal only power plant would need to produce the same amount of electric power.
Last week, at the National Clean Energy Summit 2.0 in Las Vegas, Energy Secretary Chu called for a revolution, “a second industrial revolution.” The first industrial revolution came with a “carbon dioxide cost” but “in the next industrial revolution, we must develop technologies that will enable us to get the energy the world needs to grow and prosper but “essentially reducing and eliminating the carbon dioxide,” he said. Chu said the United States has the greatest research and development centers in the world in universities, national labs and the private sector. “Once we get this great invention machine geared and going we’d be invincible. But the only trouble is, let’s get it going.”
