Guide to Purchasing Green Power
Summary
Today, the diverse array of energy resources used to create electricity can produce very different environmental
impacts. In the United States, power generation is still the nation’s single largest source of industrial air pollution and is a major contributor to greenhouse gas emissions, despite advances in pollution controls over the last 30 years1. Electricity generated from renewable resources such as solar, wind, geothermal, some forms of hydropower, and biomass has proven to be an increasingly attractive choice for electricity consumers. This Guide to Purchasing Green Power focuses on voluntary purchases of electricity generated from these renewable resources. It is intended for businesses and other organizations that want to diversify their electricity supply and reduce the environmental
impact of their electricity use. Although renewable resources can also be used for heating and cooling needs or for
transportation, this guide does not address those applications.

Technical Guide No. 4 Guide to Variable Speed Drives
This guide continues ABB’s technical guide series, describing different variable speed drives (VSD) and how they are used in industrial processes. Special attention has been given to electrical VSDs and especially to AC Drives. The guide tries to be as practical as possible. No special knowledge of VSDs is required, although basic technical know-how is required to fully understand the terms and descriptions used.

Copper for Busbars (Guidance for Design and Installation)
About this Guide
Busbars are used within electrical installations for distributing power from a supply point to a number of output circuits. They may be used in a variety of configurations ranging from vertical risers, carrying current to each floor of a multi-storey building, to bars used entirely within a distribution panel or within an industrial process.

Guide to Approval of Retrofit Ballast Water Management System Installations
PURPOSE
The purpose of this document is to give a procedure when a DNV classed ship is subject to a retrofit installation of a ballast water management system (BWMS).

Cable Diagnostic in MV Underground Cable Networks
Introduction
As an introduction we want to show how cable testing and diagnostics allow you to plan the maintenance of cable routes, thus preventing expensive power failures and significantly reducing maintenance costs for cable networks. We also list tried-and-tested measurement methods, describe these in detail and introduce various options for their use. Finally, we provide guidance on how to successfully implement diagnostics.

Emissions Trading Worldwide
Another eventful year has passed, and the urgency of addressing the climate crisis looms larger than ever before. Record high temperatures, extreme weather events, and other growing impacts serve as frequent reminders that the climate challenge is with us now: it can no longer be treated as a problem for the future. We find ourselves moving ever closer to the milestone years of 2030 and 2050, when many countries have set emissions reduction goals. Reaching these goals demands swifter and more ambitious action than ever. Analyses have shown that, in this critical
decade, we must strengthen domestic and international policy frameworks to dramatically accelerate our efforts to address climate change. We also know some amount of climate change is already incorporated into our future. But there is still time to avoid the worst impacts if we act with all the tools we have, including emissions trading.

Green Hydrogen Strategy
Roughly 100 years ago, in February 1923, futurist John Haldane delivered a lecture at Cambridge University on
wind farms that would provide England with clean and cheap electricity to produce hydrogen; he also envisioned
the use of underground hydrogen storage to supply energy when the wind was not available (Haldane, 1923).
Since then, there have been several attempts (for example, during the oil crisis of the 1970s) to scale up hydrogen,
particularly as a clean fuel to replace oil. Each occurrence of a “hydrogen wave of interest” marked a distinct
phase in the exploration and development of hydrogen as a viable energy solution.
The most recent phase is linked to international efforts to avert dangerous climate change. Countries around the
world agreed in 2015 that rapid decarbonisation is needed and adopted the historic Paris Agreement. According
to the Intergovernmental Panel on Climate Change (IPCC), human activities have unequivocally caused global
warming, and in the last decade the average global surface temperature reached 1.1 degrees Celsius (°C) above
pre-industrial levels. Based on the findings of Working Group III of the IPCC’s Sixth Assessment Report, global
temperature is likely to exceed 1.5°C of pre-industrial levels this century, based on current global targets expressed
in National Determined Contributions (NDC), and even limiting warming to below 2°C would rely on a rapid
acceleration of mitigation efforts after 2030.
