Design Race in Wind Turbine Drivetrains

The game is on. We will know in 2015 if the industry is likely to narrow down to one clear winning design, or whether there remain many routes to the same destination.

2011 Renewable Energy World Conference & Expo Report

We reached out to companies from across the industry for a peak at some of the new products that will be showcased this year. Below is a compilation of some great new products that should be an interest to you.

Single vs. Dual Axis Solar Tracking

Generally Dual-axis trackers are more accurate in pointing directly at the sun which is usually the brightest spot in the sky, however, Dual axis comes at the price of higher complexity and lower reliability ( more down time and more maintenance) than single axis.

Sanyo Smart Energy System

The "Smart Energy System" is a SANYO energy management system that includes clean, renewable energy generation, energy storage using lithium-ion batteries, smart & energy efficient appliances, cooling systems, and an energy management system that uses the energy generated and stored efficiently.

Recent Energy Report by Denver Metro Economic Development Corporation Highlights Significant Achievements for Colorado

Doing Business with China & Creating American Jobs

The role of fossil fuels and renewables will begin to meld into an acceptable state of necessary coexistence and development simply because the economics and math dictate such an outcome. But the inability to excise coal from the equation will drive the innovation cycle to make it better.

Global Small Hydro Projects in Development

The advantages of generating electricity from small hydropower coupled with a rising interest in the sector has led to increased government support policies which will derive installations in many countries in the years to come. Cumulative installed capacity of small hydropower is expected to reach 140 GW in 2015 and 201 GW in 2020.

2010 Solar Deal Volume Comparison

The transaction landscape of 2010 highlights the increasing consolidation trend within the solar energy industry. Primarily, this consolidation occurred later in the value chain with acquisitions of EPC integrators/ developers and producers of solar energy. This trend is expected to continue as companies and investors look to increase their portfolios of completed solar projects and pipeline opportunities.

A Catch-22 in the PV Connector Industry?

PV connectors are part of a system, and how well they connect and disconnect along with the ease of assembly & installation is important to installers. Electrical standards for PV connectors have been established through the National Electric Code (NEC) and UL. However no design and/or contact standards exist. The ‘defacto' standard has not been uniformly accepted by manufacturers. The need for compatibility and interchangeability is clear.

Alternate Ways to Overcome Energy Crisis in Pakistan

One of the barriers in growth of Alternate and Renewable applications is the lack of presence of one sole Energy Administration Authority for regulation of energy sector. We strongly recommend that that one Energy Administration Authority should be evolved to streamline decision making.

Choosing a Portable Renewable Energy Generator

Power generation systems have hundreds of applications. This article will focus on portable generators in specific and a range of their applications and sizing considerations in general. The intent is to address the frequently-asked questions, "What will this generator run?", "For how long?", and "Will it run my house?" Those questions usually have to be answered with the question, "What do you want (need) to run?" which defines the application.

Increased Auction Activity in Alternate Energy and Green Technology

As well as being approached to auction IP in this field of technology, IP Auctions have an increase of inquiries for this technology from corporations, IP attorneys and brokers, as well as Venture Capitalist and Seed Venture groups.
