Hydropower – Time Tested and Ready for the New Energy Era

Author(s): Scott Corwin

During an era of unprecedented change in the energy industry, hydropower offers a renewable and emission-free power source that boasts some unique attributes. Not only does hydropower provide reliable base-load generation, but it also has a high level of flexibility that enables storage and ramping capability. These qualities match well with the increasing need to balance intermittent renewable generation sources, such as wind and solar. At just seven percent of total electricity generation in the U.S., hydropower already displaces about 200 million metric tons of carbon dioxide emissions that would otherwise come from thermal generation. It is efficient in its… [more]

The Problem with Renewable Energy Subsidies

Author(s): Cutter González
Energy Project Campaign Manager, Policy Analyst

Date: December 3, 2018 at 11:37 AM

The Production Tax Credit (PTC), a federal subsidy for renewable energy, is a $24-per-megawatt-hour credit based on energy production rather than demand. That means those who produce renewable energy can receive the credit regardless of whether or not that electricity is actually needed. The incentive is so immense that at peak hours of output wind producers can actually pay retail electric providers, the companies that deliver the energy to homes and businesses, to take their product. This “negative pricing” scheme caused by the PTC and other subsidies is having serious consequences.The instability it causes can push out the energy producers that… [more]

A Bold Step Forward for Solar

Vote Solar
Date: October 29, 2018 at 11:09 AM

In May, the California Energy Commission unanimously approved the nation’s first commitment to putting solar on qualifying new home construction starting in 2020 – a move that’ll be good for our cost-of-living and our climate alike. Building solar on new homes is consistent with California’s zero net energy goals for new buildings, and it’s a great way of getting rooftop solar built cheaply for customers. When solar PV is installed at the time of construction, you get economies of scale and save big on non-hardware costs like customer acquisition, permitting and financing. Assuming modules are 40 cents/W and the other… [more]

Debate Continues Over Carbon Neutrality of Biomass

Last Monday, Scott Pruitt announced that the Environmental Protection Agency will now consider the burning of biomass for energy to be carbon neutral. The agency memo points out that the use of biomass for energy can bolster domestic energy production, reduce wildfire risk, and help ensure that forests continue to remove carbon from the atmosphere. The memo further states that “Managed forests improve air and water quality while creating valuable jobs and thousands of products that improve our daily lives.” Despite the ruling, using biomass for energy remains a contentious issue. Scientists and various non-governmental organizations have raised concerns that… [more]

Strategic Planning to Avert a Global Warming Catastrophe

Author(s): Henry M. Goldberg
Consultant
Independent
Date: December 4, 2017 at 10:00 AM

The United States and world are facing a crisis of enormous magnitude if the global warming problem is not addressed properly.  Every country in the world, except the current U.S. administration, supports the Paris climate agreement goal limiting the rise in global average surface temperature to 2°C (3.6°F).  The consequences of failure could be a catastrophic future: Flooding from rising sea levels, more severe hurricanes/heat waves/wildfires, crop failures and droughts, and greater stress on an already aging infrastructure. Climate scientists generally agree carbon emissions should be reduced to near zero by mid-century to avert catastrophic climate change. But the voluntary… [more]

Coordinating State and Federal Energy Policy in Support of Nuclear

Author(s): Dr. Andrew C. Kadak

There is an inconvenient and uncomfortable truth that nuclear energy is a significant non-CO2 source of electrical power in the U.S. Despite the dramatic expansion of solar and wind, these alternative forms of energy only provide 15% of non-CO2 emitting power nationwide. Nuclear energy on the other hand, provides 63% of all CO2-free sources. Often when a utility decides to shut down a nuclear plant it is replaced by natural gas. But replacing nuclear with “clean” natural gas only adds to the global CO2 load. In fact, each 1,000 megawatts of nuclear power replaced by natural gas adds 3.6 million… [more]

The Case for Nuclear Central Station Power

Author(s): David Hammer
J.C. Ward Jr. Professor of Nuclear Energy Engineering
Cornell University
Date: September 9, 2015 at 9:30 AM

 “Sustainable future” advocates seem to believe that solar, wind and hydro-electricity will eventually make up close to 100% of our energy generation, but there are benefits to having “central station” power plants in addition to distributed power generation. If the goal is to reduce greenhouse gas (GHG) emissions while assuring the health of our economy, the most viable way of generating central station power at present is nuclear fission. Central station power complements distributive power generation in two important ways.  Central station power plants are better able produce power on a small area relatively close to where the energy will… [more]

A Regional Approach to Offshore Wind?

According to The Department of Energy (DOE), the United States has 4,000 GW of offshore wind energy potential, with the strongest winds located off the North Eastern Atlantic Outer Continental Shelf (OCS). There are currently no operational offshore wind farms in the country, but the Bureau of Ocean Energy Management (BOEM) has identified 18 states which are involved in early stage offshore wind projects. High profile offshore projects like Cape Wind have faced stiff opposition over the last decade and the first project to begin construction, Block Island, has only recently done so. Utilities and regulators have raised concerns about… [more]

The Role of Innovation in Meeting the EPA’s Clean Power Plan

Author(s): Peter Kelly-Detwiler

Date: May 12, 2015 at 8:00 AM

The EPA’s proposed Clean Power Plan, meant to reduce carbon by 30% by 2030, is expected to be accomplished through a combination of improving existing power plants, switching to cleaner generation, boosting renewables, and improving energy efficiency. It is more than likely that the global economy’s ability to innovate and drive economies of scale will significantly ease this transition, providing as yet unknown but superior alternatives. Consider this: the wind and solar industries barely existed five years ago. Today, costs of wind have fallen by 58% in the last five years, and the price of installed solar has plummeted by… [more]

Full Title: EROI of different fuels and the implications for society Author(s): Charles A.S. Hall, Jessica G. Lambert, Stephen B. Balogh Publisher(s): Elsevier, Energy Policy Publication Date: 2014 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): All forms of economic production and exchange involve the use of energy directly and in the transformation of materials. Until recently, cheap and seemingly limitless fossil energy has allowed most of society to ignore the importance of contributions to the economic process from the biophysical world as well as the potential limits to growth. This paper centers on assessing the energy costs of modern day society and its relation… [more]
