Our increasing reliance on natural gas brings with it both opportunities and dangers during the shift towards renewable energy. This issue deals with some major issues regarding natural gas deployment in industry, power generation, food production, and heating.

A renewed look at 2010, a sustainable vision for 2011
Here we review major renewable energy topics from 2010 and then turn towards analyzing energy issues for 2011 and beyond.
Demand side management to help build a renewable power grid
Demand side management helps make our power grid more cost-effective and aids in the transition towards renewable energy. It can also be considered as a very green policy on its own, as it reduces the amount of power we need to produce, and thus our impact on the environment.
Power system performance metrics
Everything has its price. Every form of power production has costs in dollars, time, land, materials, pollutants, greenhouse gas emissions, and human deaths. We look at the most important factors for analyzing the feasibility of a proposed power project. Considering only some of these factors will lead to an incomplete picture of power system costs.
Feed-in tariffs: A fitting policy for renewable energy
Here we talk about what a feed in tariff is and how it works. We also conduct an overview of how effective feed in tariffs have been at stimulating the renewable energy industry around the world.
How can renewables deliver dispatchable power on demand?
What does dispatchable mean? Why is it important? How do we currently do this? Can renewable energy fulfill this role? What other tricks can we use?
Land use of coal vs wind: Still room for debate
Land usage for power systems is a common comparison metric. We demonstrate here that the comparison cannot be conducted meaningfully on such simplistic grounds. Additional factors must be taken into consideration.
The regulatory battle over coal fly ash heats up
The coal industry has had a history of lobbying against a hazardous waste label for fly ash. Fly ash is toxic enough that the EPA mandated decades ago that it be captured and stored rather than emitted into the atmosphere.
Misconceptions spreading about the price of solar power
A recent Clean Technica article said that solar power would be cheaper than coal if it received the same subsidies. This is incorrect.
Progress and potential of renewable energy
The intent of this publication is an ongoing investigation of the progress and potential of renewable energy in our world. Our goal is to collect the best writing and news on the subject of renewable energy projects and policies. We have observed that humanity is innovating rapidly as the energy security of the future becomes a global priority. Current trends indicate that the age of coal will end before we run out of coal.
Renewable Energy Review Blog Carnival
Vision of Earth is the host of the newly created renewable energy review. This is a blog carnival attempting to look at the development of renewable energy in the world today. Submitted articles will be judged on their quality, accuracy, and relevance. Once enough high-quality submissions are accumulated for a publication, our editors will write a brief review piece, linking to these novel contributions. We intend to comment meaningfully on the developments in renewable energy in our world.
Publicly Administered Green Energy Futures
Our goal is to keep our physical power infrastructure publicly owned, but gain some of the advantages of the private sector. The key to our recommendation is voluntary public investment from the people of Saskatchewan. In order to stimulate new renewable energy construction, we recommend that SaskPower open up renewable energy projects for direct public investment.
Personal and social change for a green energy future
The question is: what can we do to be more in harmony with the environment? The answers we present here are intended to be practical pieces of an answer to that question.
Solar Thermal Power
Solar thermal power generation presents a unique opportunity among renewable technologies today. It is well-understood. Prototypes and commercial power plants of this sort exist. It has capabilities for both baseload and peak-matching power generation. It is affordable in locations with lots of sunlight. Costs are in the range 10-15¢/kWh currently, with great potential for the future.
