Micro Inverter or the AC-Module Inverter: Truths vs. Myths

When it's time to choose an inverter for a PV system, the system owner and the installer have the choice to use a string inverter or micro inverters for the installation. It is important to realistically assess the viability of this technology.

NanoPioneers Are Becoming the New Environmentalists

A new type of environmentalist is emerging, using nanotechnology based products as a way of reducing their impact on the environment and reducing their energy use in a variety of ways.

AltEnergyMag Interview - Data Privacy and the Smart Grid

With the advent of "home area networks" which allow consumers to be able to see what they are using in real time and make adjustments and decisions accordingly, this data could potentially be used by third parties to assist the consumer with those decisions. It will be important for that information to have privacy provisions built in so that third parties cannot access the data for purposes that have not been authorized by the consumer.

Distributed Energy Production And The DIY Movement

A distributed model revolutionized the way industrial-scale computing was delivered. Is it possible that something similar could be achieved for energy production?

Interview - Using Hard Disk Technology to Manufacture Solar Cells

XsunX is combining its thin-film photovoltaic (TFPV) process knowledge and processes with magnetic media thin-film manufacturing technologies used by the hard disc drive industry to mass produce high efficiency, low cost solar cells. Current techniques for the production of CIGS thin-films do not leverage stationary small area, high rate, production technologies which allow for the precise control of thin-film properties.

Introduction to Solar Light-Generated Hydrogen Production Technology

Phoenix is maintaining a material investment program in a research and development program targeting the production, from virtually inexhaustible hydrogen resources, the "replacement" fuel for applications we consider, both technically and economically, as beyond the many "alternative" energy solutions advanced in recent years to respond to the world's accelerating energy deficit.

Solar Cities Proposition

"Buildings like trees, cities like forests." When Michael McDonough, author and sustainability architect, suggested this be the new paradigm for the future, he was referring to the creation of buildings and communities that are self-sufficient. He also reminds us that "waste is a human phenomenon", so the concept of recycling and efficiency is central to the attainment of environmental stewardship. Through integration, energy management, efficiency techniques and technologies it is now possible to create buildings that are 'greener' and more ecologically synergistic than ever before.

The Solar Power Paradox: Alternative Energy Can't Run on Oil

As the PV business continues to grow, new backsheet constructions are continually being introduced. But the products we use in our efforts to be more sustainable have a bigger footprint than we think. Currently, there are at least ten commercial manufacturers of traditional PV backsheets, with traditional products in the development stage. Traditional backsheets, the protective covering on solar cells, are produced mainly from polyester and Tedlar films. Polyester is made from petroleum and Tedlar is solvent-cast using DMAC, a highly toxic industrial solvent. Both of these products defeat the purpose of clean, green energy, and as the demand for solar energy increases, so does this issue.

Superconductor Electricity Pipelines: An Optimal Long-Haul Transmission Solution

While the United States is rich in renewable resources for the production of green electricity, expansion and modernization of the North American power grid will be required to transmit that power to where it is needed.

COGENERATION FACILITY AT 102% EFFICIENCY

Remember the First law of thermodynamics? Energy can neither be created nor destroyed. It can only change forms. Or, if translated into an idiot-proof rule of thumb: you can't go above 100%. Remember this? Now forget it; this law has got a loophole.

THE HISTORY OF HYDROGEN

One of the most serious gases we must use is Hydrogen - in our cars, buses, Space shots from the cape etc. I have been studying Hydrogen, Propane and many Bio-fuels and have found hydrogen to be the best, the oldest and the cleanest. I feel this alternative product is a win -win.

ECO-SHEET COMPARES ENERGY SOURCES

The eco-sheet shows that there is no silver bullet solution. When looking at CO2 emissions only, it would be clear what options to take. However, this is not the only environmental consideration. Not preferring any particular method of electricity generation, the eco-sheet lists the main environmental impact categories and benchmarks them against the electricity generation mixes for the EU 25 and EU 15.

WIRELESS SENSOR NETWORKS FOR A GREEN WORLD

Ultimately, battery-free operation is a key step in paving the way for truly green systems that do not adversely impact the environment. This environmentally-friendly approach can also extend the reach of sensing technology to distant and inhospitable climates and regions.

HPCC A GREEN ENERGY ENABLER

HPCC's energy efficient applications, such as networking thermostats in homes and demand control, remote management of high power appliances, etc. ensure a more environmentally friendly future.

THE EUROPEAN MARINE ENERGY SECTOR

The marine energy industry has a long way to go but ongoing research and government support should lead to improvements making these technologies more economically attractive in the future. Combined with intensifying company activity in this field, Europe is poised to be the place to watch in the marine energy arena of the future.
