SRP (Salt River Project) is a public utility providing electricity and water to parts of Arizona. The document discusses SRP's sustainability initiatives including their renewable energy portfolio, energy efficiency programs, and EarthWise customer programs. SRP gets 47% of its energy from coal, 32% from natural gas, and 15% from nuclear, with the goal of obtaining 15% from sustainable sources by 2025 including solar, wind, hydroelectric, biomass and more. SRP implements various rebate programs to promote customer energy efficiency and use of renewable energy.

Update on implementation of Cape Town's 2009 Responsible Tourism Policy on occasion of 10 yr commemoration of signing of Cape Town Declaration at South Africa House, 21 June 2012
Governor Murphy, through Executive Order 28, has set New Jersey on the path toward transitioning to 100% clean energy by 2050.
In June, the Board of Public Utilities (BPU) issued a draft of an updated Energy Master Plan (EMP) that encompasses a dramatically broader scope than previous EMPs, and features a series of seven strategies that will guide the state to address the imminent threat of climate change and to reach Governor Murphy’s 100 percent clean energy goal.
This timely webinar features experts who will provide an overview of the EMP draft, and how it has the potential to result in significant economic benefits, including the creation of new jobs, industries and workforce development opportunities for the state’s residents and business community.
The NJ BPU is accepting comments on the EMP draft until September 16th. Please join us so that you can add your voice with others in the sustainable business community to help make the EMP a strong and effective roadmap to creating a clean energy economy.
202 solar solutions debunking economic v-environmental rationale for solarAnthony Pentleton
A short presentation on debunking the economic versus environmental debate about solar, demonstrating an economic stalemate. One that highlights the clear swing favoring the environment, funded by the home owner through government incentive.
Energy efficiency is a power house job creator. Recent research from ACEEE finds that changes to Pennsylvania’s energy efficiency laws could deliver more than 30,000 jobs to the Commonwealth. What do these jobs look like, and how do we make them a reality?

Meeting the targets to keep warming below 2°c a new us pathwayLuca Soppelsa
The US "Clean Power Plan" is insufficient for a 2°C pathway.
We need:
- Holistic and stringent Federal policies to attain targets;
- Threefold approach where renewable electricity plays a key role;
- Policies need to promote new energy investments;
- Immediate action to minimize the costs;
At the UN Climate Summit in Paris, policy-makers, businesses and financiers together can make the change happen.
