Catching the Wind: State Actions Needed to Seize the Golden Opportunity of Atlantic Offshore Wind Power

Monday, July 21st, 2014
EAST COAST ENERGY GOLD MINE

NATIONAL WILDLIFE FEDERATION
The Atlantic coastline is at the epicenter of America’s energy and environmental challenges, with state leaders currently facing critical decisions to meet the region’s growing energy demands and protect our communities and wildlife from the impacts of climate change. The cities, metropolitan areas, and sprawling suburbs that stretch along the East Coast have a massive, pollution-free energy source ready to meet these challenges –– offshore wind.

Features of a Fully Renewable US Electricity System: Wind and Solar PV

Thursday, July 3rd, 2014
Figures 1 and 2

STANFORD UNIVERSITY
DEPARTMENT OF CIVIL AND ENVIRONMENTAL ENGINEERING
CO2 and air pollution emission reduction goals as well as energy security, price stability, and affordability considerations make renewable electricity generation attractive. A highly renewable electricity supply will be based to a large extent on wind and solar photovoltaic (PV) power, since these two resources are both abundant and either relatively inexpensive or rapidly becoming cost competitive. Such a system demands a fundamentally different design approach: While electricity generation was traditionally constructed to be dispatchable in order to follow the demand, wind and solar PV power output is largely determined by weather conditions that are out of human control.

Global Infrastructure Spending: Outlook to 2025

Thursday, June 26th, 2014
Figure 1: Five key infrastructure sectors

PricewaterhouseCoopers (PwC)
Infrastructure spending has begun to rebound from the global financial crisis and is expected to grow significantly over the coming decade. That is the main finding of Capital project and infrastructure spending: Outlook to 2025, our in-depth analysis of 49 countries that account for 90% of global economic output. Worldwide, infrastructure spending will grow from $4 trillion per year in 2012 to more than $9 trillion per year by 2025. Overall, close to $78 trillion is expected to be spent globally between 2014 and 2025. But the recovery will be uneven, with infrastructure spending in Western Europe not reaching pre-crisis levels until at least 2018. Meanwhile, emerging markets, unburdened by austerity or ailing banks, will see accelerated growth in infrastructure spending, especially China and other countries in Asia.
