One of the reasons that hasn happened yet is because of funding limitations facing early-stage cleantech companies.
The committed funds are more than double the goal of the President Obama Clean energy Investment Initiative that was announced earlier this year.
said Biden. ur energy future is in cleaner, cheaper renewable energy. A new organization, PRIME Coalition, is committed to helping foundations manage the complex pipeline process of vetting candidates and helping to lower transaction costs for foundations,

most current forecasting techniques rely on individual weather models that offer a more narrow view of the variables that affect the availability of renewable energy.
IBM approach provides a general platform for renewable energy forecasting, including wind and hydro. It advances the state-of-the-art by using deep machine learning techniques to blend domain data,
That can increase the use of renewable energy sources as a more accepted energy generation option, said Dr. Bri-Mathias Hodge,
who oversees the Transmission and Grid Integration Group at the National Renewable energy Laboratory (NREL), a collaborator in the project.
In 2013, solar was the second-largest source of new electricity generating capacity in the U s,
. exceeded only by natural gas 1. A USA Sunshot Vision Study suggests that solar power could provide as much as 14%of U s. electricity demand by 2030 and 27%by 2050 2. Currently,
there are two main customers for renewable energy forecasting technologies: utility companies and independent system operators (ISOS.
With solar power installations rapidly growing, future solar penetration levels will soon require increased attention to the value of more accurate solar forecasting.

#Technology Fuel cells provide electricity for homes Kyoto-based Steven Rogers is the business development executive for Ceres Power, a British venture company that specialises in solid oxide fuel cells.

Then, the electricity has to travel by cable and pylon to the consumer, with an additional 20%of energy lost along the way.
By the time the electricity reaches the home, only 40%of the original energy remains. eat is wasted always

#Wind turbines Without Blades It no longer surprising to encounter 100-foot pinwheels spinning in the breeze as you drive down the highway.
A Spanish company called Vortex Bladeless is proposing a radical new way to generate wind energy that will once again upend
a bladeless wind turbine that looks like a giant rolled joint shooting into the sky. The Vortex has the same goals as conventional wind turbines:
To turn breezes into kinetic energy that can be used as electricity. But it goes about it in an entirely different way.
Instead of capturing energy via the circular motion of a propeller, the Vortex takes advantage of what known as vorticity,
This kinetic energy is converted then into electricity via an alternator that multiplies the frequency of the mast oscillation to improve the energy-gathering efficiency.
which stands at around 41 feet tall, can capture up to 40 percent of the wind power during ideal conditions (this is
Based on field testing, the Mini ultimately captures 30 percent less than conventional wind turbines, but that shortcoming is compensated by the fact that you can put double the Vortex turbines into the same space as a propeller turbine.

Since a diode acts as an electricity valve, its structure needs to be asymmetric so that electricity flowing in one direction experiences a different environment than electricity flowing in the other direction.
In order to develop a single-molecule diode, researchers have designed simply molecules that have asymmetric structures.""While such asymmetric molecules do indeed display some diode-like properties,

#Chemists devise technology that could transform solar energy storage The materials in most of today's residential rooftop solar panels can store energy from the sun for only a few microseconds at a time.

The new design is inspired by the way that plants generate energy through photosynthesis. iology does a very good job of creating energy from sunlight
To capture energy from sunlight, conventional rooftop solar cells use silicon, a fairly expensive material. There is currently a big push to make lower-cost solar cells using plastics
rather than silicon, but today plastic solar cells are relatively inefficient, in large part because the separated positive and negative electric charges often recombine before they can become electrical energy. odern plastic solar cells don have well-defined structures like plants do

"But with the micro-reactor, some signals were too small to detect. Particles smaller than a single nanometer were hidden behind

"Versatile micro-reactorthe new micro-reactor was designed specifically and built to work seamlessly with both synchrotron x-rays and electron microscopes."
"Brighter, faster experimentsthe collaboration has extended already this operando micro-reactor approach to incorporate two additional techniques-infrared
but other new micro-reactors can operate at up to 800 degrees Celsius-more than hot enough for most catalytic reactions
In the near future, this same micro-reactor approach will be used to explore other crucial energy frontiers,
and storing solar energy into hydrogen. Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems.
To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen,
the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize.
EPFL scientists have developed now a simple unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.
The work is published in Nature Communications. Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies
However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale
called ungsten diselenide Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel
which is much less expensive than a traditional solar panel. The thin film produced like this was tested
#Reshaping the solar spectrum to turn light to electricity Researchers find a way to use the infrared region of the sun's spectrum to make solar cells more efficient.
When it comes to installing solar cells, labor cost and the cost of the land to house them constitute the bulk of the expense.
The solar cells made often of silicon or cadmium telluride rarely cost more than 20 percent of the total cost.
Solar energy could be made cheaper if less land had to be purchased to accommodate solar panels, best achieved if each solar cell could be coaxed to generate more power.
A huge gain in this direction has now been made by a team of chemists at the University of California
Riverside that has found an ingenious way to make solar energy conversion more efficient.
