CCS and Carbon Negative Solutions

If climate science proves to be correct and the 450 ppm scenario is confirmed as a global priority in the medium-term future, we will probably require a very large scale deployment of CO2 negative technologies from the middle of this century. According to the IPCC, CCS will play a very important role in this regard.[read more]

Renewable Wood Fuel and Overall Cost

Wood is considered either a renewable fuel with environmental benefits or a source of particular material emissions that can impact health. If properly managed can the smoke from wood be reduced to levels that mitigate current-future health issues, and benefit the environment like other renewable fuels?[read more]

Clean Energy and Efficiency Support in Virginia

“What’s amazing is the stranglehold the coal industry and Dominion Power have over Virginia’s political system,” said political commentator Lowell Feld. “It’s frustrating because there is huge potential for renewable energy in this state. These industries can hang for on a long time. It’s difficult to uproot them.”[read more]

Biomass and Renewables

If I asked you to think of renewable energy what comes to mind? I imagine it is skyscraper-sized wind turbines, solar panels on suburban roofs or massive hydro-electric dams. You probably do not think of burning wood or converting crops to liquid fuel to be used in cars.[read more]

Ethanol Imports and Emissions

The ‘Renewable Fuel Standard’ (RFS) requires blending biofuels into motor fuels annually to reduce petroleum consumption and associated carbon emissions. Since 2010 RFS compliance has included Brazil sugarcane ethanol imports. Do these imports actually achieve RFS carbon reduction requirements?[read more]

Biofuel Ideas

Along with other forms of so called “renewable energy,” I have come to hold a jaundiced view of biofuels, largely because of their inevitable competition with food supplies, as well as some concern about land use and the pressure placed on natural habitats.[read more]

Why Biofuels Tend to be Costly

March 14, 2014 by Robert Rapier

Photosynthesis is a very inefficient process. Solar energy is converted into biomass at a rate of only 1 percent or so, which is a fraction of the energy conversion that can be achieved with a solar panel. An advantage of photosynthesis is the biomass that is produced is built-in energy storage.[read more]

When Renewables Destroy Nature

The case against using trees and crops as fuel for cars and power plants has grown stronger in recent years. The expansion of corn for ethanol in the American Midwest has worsened water pollution and soil erosion and has had no benefit in terms of reduced emissions, for example.[read more]
