Case Study: Thomonde Hospital In The Central Region of Haiti

The Thomonde battery bank was designed for 40 percent depth of discharge and only one day of autonomy due to the large loads of some of the medical equipment and the availability of the diesel generator.

Making the Switch: From Fixed to Solar Tracker

I compared the cost per watt to install a standard pole mount, such as a DPW, and found it cost the same as putting up a standard tracker. And of course by tracking you get the additional power.

Interview with Sophie Parker of The Nature Conservancy

In areas of the Mojave that are ecologically intact, renewable energy development poses a major problem for plants, animals, and other species. Some major issues include: habitat destruction and fragmentation, water use, and bird mortality.

Data Loggers Bring More Light to Remote Medical Clinics

The WE CARE Solar team required a better way to log system performance data and monitor usage patterns to ensure that correctly-sized PV power systems were being implemented in the medical clinics.

The End to the California Solar Initiative (CSI)

Decreasing incentive over time will help build resilience and not inflate the market. It is also important to offer varying levels of incentives for residential, commercial, affordable housing, and non-profit in order to ensure equality for the benefits of solar, and help those who need it most.

Energy Management System with Certificate and Certification Mark

SIMONA AG is one of the first companies in the plastics industry to have introduced an energy management system in accordance with EN ISO 50001. Energy management systems (EnMS) offer a systematic approach to recording and assessing energy demand and improving energy efficiency. Third-party assessment and certification by TÜV SÜD offers further opportunities.

Case Study - Home Solar Panel Installation Leads to 115% Savings!

The photovoltaic home solar panel array was installed in October of 2011. The system was designed to offset approximately 77% of the annual home power bill with an average savings of around $200 dollars per month over the 40 year expected life of the system.

Overview of Carbon Capture

Carbon Dioxide Capture and Storage is a transitional technology mitigating climate change as we implement proven alternative energy technologies.

Fuel Cells Backup Critical Infrastructure

Fuel cells help reduce grid dependency and mitigate financial losses from power outages while keeping critical infrastructure up and running. No longer an environmentalist's pipe dream, fuel cells' reliability, scalability and wide range of fuel sources are saving money for companies in a variety of industries, and making dependable access to emissions-free power a reality.

Lithium-Ion Energy Storage Safety

Energy storage systems, like any energy or power system, carry some degree of risk. With today's technology, these risks are largely understood and can be effectively reduced or mitigated.

Potential risks of smart grids are underestimated

According to the study 'Security & Safety in a Smart Energy World', presented by TÜV SÜD at the opening of the 2013 Hannover Messe, the energy and manufacturing sectors are underestimating the potential risks involved in modernising power grids; awareness of the vulnerability of smart grids is negligible and protective action is rare.

Leading Edge Erosion on Wind Turbines

Awareness is growing in the wind industry about the severe impact that blade leading edge erosion can have on wind turbine output. Recent research shows that erosion can lead to a loss in annual energy production (AEP) of up to 20 percent, costing thousands of dollars.

Lessons Learned: Collaboration, Empowerment and Vigilance Key to Sites' Successful Safety Culture

It takes more than perfunctory "safety moment" sharing and hard hat stickers to ensure employees and contractors make safety their top priority. In creating a viable safety culture, site leaders first identified the unique strengths of each company and exchanged lessons learned at other power generation facilities.

CHINA FACES $243BN CLIMATE FINANCE "GAP" PER YEAR BY 2020

Series of reforms being explored as China seeks to expand clean tech investment

A New Class of Rogowski Coil Split-core Current Transducers

Until now Rogowski coils have delivered at best a 2% positioning error. With this improvement, the error due to the positioning of the conductor is specified at a maximum of 0.65% of the measured value for a 15mm diameter conductor irrespective of where it is positioned, even if it is adjacent to the coil clasp.
