2015 Electric Industry Report DG at the Core of Electric Industry Transformation
The 2015 electric report finds that increasing customer interest and adoption of solar, energy storage, and distributed generation is causing more utilities to rethink their approach to these resources. New technologies are enabling customers to substantially lower power consumption and potentially even go offthegrid. As a result, electric utilities are revisiting their approach to planning and becoming more proactive about the integration of distributed generation into their business models. Energy storage technologies are also changing how electric utilities function. Third parties, such as Tesla, are leading the charge and providing battery storage options to commercial and industrial utility customers. While some.
Utilities might view distributed generation as a threat, others are open to investments in it and related technologies. About 75 percent of survey respondents are thinking about investing in behind the meter and distributed grid infrastructure. Twothirds say they will increase their renewable energy generation investments in the next five years. As electric utilities continue to prepare for the changes sweeping the industry, the ability to plan and evolve will be directly tied to readiness. While no one can fully predict outcomes, Black Veatch recommends that where DG is concerned, electric utilities begin to gauge their ability to transition.
Judith de Patoul Fast solar wind from coronal holes to interplanetary space
So the sun, as we usually think of it is a big ball a yellow, iconic ball. Very quiet, romantic. as you could imagine at sunrise. Actually, the sun is much more active. Here you see the sun rotating and evolving in time with a lot of activity. This activity is generated by a magnetic field which pops out into the atmosphere the solar atmosphere, also called the corona. We can see some very bright regions where activity is very intense. But we can also see some darker regions that appear slightly quieter.
Slightly. darker. I am actually studying those particular regions. What we know about those regions is that they are large and that the magnetic field is open where the solar material can escape. A bit like a window. An open window where the solar wind can flow out of the corona. What we don't know is exactly how they form how they evolve in time and how they vanish. This solar wind, is a fast constant wind that blows out of the corona to reach the Earth. On its way to the Earth, it carries a lot of solar material.
A lot of particles. These particles can interact and damage satellites or more specifically, solar panels. They can damage and destroy some of the solar panel cells. It can also disturb and interact with technology and all devices worn by astronauts. It can reach the Earth and can disturb power plants and networks. Another example is communications, for example in plane companies. In the future we want to learn more about solar wind and space weather that is generated. Also for the future, for the exploration of space in the years to come.
TATS 2MIN NEWS November 24, 2013 COMETS ISON IN THE SOLAR WIND
CHANCE OF FLARES NOAA forecasters estimate a 25 chance of Mclass solar flares today. The most likely blastsites sunspots AR1904 and AR1905 are not, however, facing Earth. Any eruptions this weekend will probably miss our planet. Solar flare alerts text, voice COMETS IN THE SOLAR WIND NASA's STEREOA spacecraft is monitoring Comet ISON as it approaches the sun for a close encounter on Nov. 28th. The latest movie from the spacecraft's Heliospheric Imager captures not only Comet ISON but also Earth, Mercury, and Comet Encke. to set the scene in motion.
In the movie, which spans a two day period from Nov. 19 to Nov. 22, the sun is to the right, offscreen. The dark 'clouds' coming from that direction are density enhancements in the solar wind, and these are what are causing the ripples you see in the comet tails, explains Karl Battams of NASA's Comet ISON Observing Campaign. Although the two comets seem to be experiencing the same solar wind, their tails ripple differently. Encke has kind of long waves in the tail, whereas ISON's seems almost like highfrequency puffs, points out Battams.
Appearances notwithstanding, the two comets might be in two different streams of solar wind. The most likely explanation is that ISON is in a faster stream, he comntinues. Imagine holding a flag on a slightly breezy day. The flag will waft gently in the breeze. Now imagine holding it in really strong winds. The flag will be rippling violently, but those ripples will be smaller in amplitude. Battams also suggests a second, more speculative possibility. You can read about it here. Realtime Comet ISON Photo Gallery COMET ISON, T4 DAYS Comet ISON is now only 4 days from perihelion. On Nov, 28th, Thanksgiving.
Day in the USA, it will fly through the sun's atmosphere little more than a million kilometers above the surface of the sun. At closest approach, the temperature of ISON's core could rise as high as 5000o Fahrenheitan existential challenge for an icy comet. No one knows if it will survive. As the final countdown ticks to zero, photographers are taking some marvelous parting shots. Here is Comet ISON plunging into the sunrise beside Mt. Fuji on Nov. 22nd Japanese photographer Kagaya took the picture using a Canon EOS 1D C digital camera. This.
ES Subs NASA Planetary Science Studying the Solar Wind on Mars HD
Mars's atmosphere is much less dense than the Earth's, it only has about one percent of the density of the Earth's atmosphere. However, we're pretty sure that Mars had a much thicker atmosphere in the past, because there's such strong evidence for running water on the surface, and to have running water, Mars's atmosphere had to be much thicker. Now MAVEN is going to look at how Mars lost its atmosphere, in particular whether it could have lost its atmosphere to space. My name is Bob Lin, I'm a professor of physics.
And I work at the Space Sciences Laboratory of the University of California at Berkeley. MAVEN is a Mars Scout mission for NASA, and it's an orbital mission to Mars which is designed to study the loss of the atmosphere of Mars. For example if there was a large solar eruption, if the solar wind increased in strength, we could then look at how the atmosphere gets lost in each of these situations. Because Mars is in the solar wind, a lot of the loss comes from these ions and electrons that are escaping,.
And the Particles and Fields package is designed to look at the escape of the charged particles from the atmosphere. We have the Solar Wind Ion Analyzer, which measures the incoming solar wind, then we have the Solar Wind Electron Analyzer, which measures the incoming solar wind electrons. We have the Langmuir Probe and Waves instrument, and that measures solar ultraviolet. It also measures lowenergy electrons that might be escaping from Mars, and furthermore it measures waves that might be accelerating the ions so that they can escape from Mars. We then have the STATIC instrument.
It will give us the composition of what is escaping, whether it's CO2, or hydrogen, or helium and so forth. The Solar Energetic Particle instrument, SEP, measures highenergy particles from the Sun, and those particles will hit the atmosphere and cause a lot of damage. And finally there's a magnetometer, which will measure the magnetic field in the solar wind and the magnetic field of Mars. Mars is the only planet, besides the Earth, where you really have a chance that life might have formed. The conditions for life are water, running water,.
2015 Electric Industry Report EPC Accelerates Project Delivery
The 2015 electric report finds growing use of alternative delivery systems like engineering, procurement and construction, or EPC. More project owners are realizing the benefits of an endtoend solution that rolls these three phases into a single contract. Trend lines among organizations employing EPC continue to rise. With projects ranging from traditional power generation to solar, wind and distributed generation technologies, EPC is becoming an industry standard. Respondents to our survey say scheduling and cost certainties are significant advantages of the EPC delivery model. Project owners also enjoy the performance benefits.
Associated with having a single point of contact throughout the life of a project. Collaboration and flexibility in financing are also important draws for project owners. As energy providers explore their next large infrastructure project, their most important decision may rest with the selection of the EPC provider. Firms that employ lean practices by eliminating wasteful and redundant processes can provide significant paybacks to a project owner. Firms should also be considered for their track record and commitment to safety. Another key consideration is owner involvement. Some in the industry suggest the EPC approach removes control from.
Comparing Midnite Solar Classic MPPT solar charge controllers
Hi, I'm Amy from the altE Store. We're going to take a look at the Midnite Solar Classic MPPT solar charge controller family. There are 9 models, easiest to describe divided into two criteria, voltage and current range, and feature set. All models are made right here in America. The Classic is available in a 150V DC 96A, 200V 79A, and 250V 63A model. I have here a sampling of the models, the Classic 250, Classic SL150, and Classic Lite 200. All models will charge battery banks from 12V to 72V. The whole Classic Line has MidNite's HyperVOC feature which extends high voltage.
Input limits when needed. With HyperVOC, because the voltage of silicon solar panels goes up when it gets cold, if it happens to get colder than you designed for, and the voltage of your solar array goes higher than is safe for the Midnite Classic charge controller, instead of getting damaged from the high voltage like other charge controllers would, it will put itself into a nonoperational self protect mode until the panels warm up and the voltage drops back into the safe range. Within each of those voltage and current ranges,.
There are also 3 levels of features available. They are like the Goldilocks and the 3 bears of charge controllers. The Classic is their full featured model. It has Solar, wind and hydro maximum power point tracking modes. It has a display for configuring and monitoring your system and push button programming. It's got ethernet capabilities to remotely monitor and configure your charge controller, and datalogging capabilities. The Classic also has Ground Fault Protection and is one of the few charge controllers in the industry to have Arc fault protection. The Classic Lite is a stripped down version.
Of the Classic. It can also be used for solar, wind, or hydro. But instead of the graphical display screen for viewing and programing, it has an LED indicator panel with DIP switches. The Classic Lite also comes with the free full featured software to allow you to program, log and monitor the Classic via a PC or ethernet. It does have ground fault protection, but does not have arc fault protection. The lite is a perfect solution when you have 2 or more Classics in the system, one can be the full featured Classic, and the others can be the.
Lite, since only one of the Classics in the system needs to have the meter to monitor the entire system. It also is a great solution if you are using the remote display, so you can monitor your system from your living space, while the charge controller is in the utility room. The newest Classic SL is juuuust right in the middle.It does not have wind or hydro capabilities. It is a simplified solar only version of the Classic with streamlined menus. The Classic SL has the graphics panel and ground fault but no arc fault or Ethernet capabilities.
This is the perfect charge controller for you if you have a solar system that you do not need arc fault protection or remote monitoring from a PC or the internet,or, you have multiple Classics, and only need the ethernet on one of them to remotely monitor the system. I hope this helped you understand how to choose the right Midnite Classic for you. Please like and share this tutorial, and subscribe to our altestore channel so we can notify you of new tutorials.
