Producing Energy from Vibrations
Hypothetically, all vibration energy can be transformed into electrical energy; but there are certain types of vibrations that are preferred when the intent is to power a sensor or monitoring system. These vibrations need to have a steady vibration and a controlling frequency.
How Silicon Carbide is Changing Solar Power Systems
Silicon carbide enables solar inverters to be lighter, smaller and more efficient. Using silicon carbide power components instead of silicon for solar inverters can save 10 megawatts for each gigawatt and 500 watts/sec in operations, representing significant energy savings.
The Evolution of Solar Technology - How Photovoltaic Technology Has Developed and Why Nanotechnology May Influence the Future
Here, Dr Franky So, chief technology officer of nanotechnology research company Nextgen Nano, explains the historical developments of photovoltaic technology and looks to the innovations shaping the years ahead.
Improving Deep-Cycle Batteries Through Additives
Battery manufacturers have improved deep cycle battery performance through the use of additives, but not all of them result in the same benefit to customers.
Automatic Charging of EVs
Charging stations can be an eyesore in inner cities, and the bulky cables and plugs can also be an inconvenience in people's garages. Contactless inductive charging with coils embedded in the garage floor or the road surface has none of these visual or mechanical annoyances.
NREL Six-Junction Solar Cell Sets Two World Records for Efficiency
The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.
IDTechEx Research: Redox Flow Batteries' Advantages for Stationary Energy Storage Market
One of the main characteristics of this technology is the decoupled energy and power capacity. In fact, while the energy is stored in the electroactive species present in the electrolyte.
The Most Exciting Green Startups To Watch In 2020
The sharing economy has become an unstoppable force--and the collaborative, peer-to-peer economy has grown from a curious fad into the trend-to-beat-all-trends over the past decade.
SMALL WIND TURBINES FOR THE ENERGY SUPPLY OF THE FUTURE
Small-scale wind energy is still in the beginning phases in Germany. Yet interest in this technology is gaining traction in light of rising electricity prices and the sociopolitical direction we are heading in to invest more in renewable energies in the future.

Over the next 5 to 10 years, renewable energy will assume a more prominent role as a main power source for power grids. Solar power, in particular, as the most noteworthy form of renewable energy, has a particularly bright future.
NREL Research Boosts Stability of Perovskites, Helps Silicon Solar Cells
A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell developed at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL).
New Solar Technology Could Generate Power at Night
This technology could represent a turning point in sustainable power. Scientists have been working for decades to make our way of life more environmentally friendly. One of the most critical aspects of this effort is to generate reliable alternative energy.
Crystal Paint for Solar Panels Could Innovate Renewable Energy
Now, researchers have developed a new way of creating solar panels that may make it easier to install than ever before - a crystal-based liquid that has allowed researchers to effectively paint on solar panels to suitable surfaces.
Dye Sensitized Solar Cells Is the Future of Solar
The dye sensitized solar cell can produce electricity under low light conditions, including indoor lighting. Due to the structural design and different color dyes, the cell features colors and transparency.
Top Article from 2019 - Traffic Powered Wind Turbines
