'Combined heat and power' (CHP) plants and 'district heating' systems have been around for well over a hundred years. And yet, only a handful of modern cities and towns have made use of these highly efficient technologies until very recently. Now that we've rediscovered CHP and district heating, what role will they play in retrofitting our economies to rely on local energy?

Cleveland's new bus rapid transit project, the Health Line, is already a great boon to the city and represents a model of wise infrastructure investment.

The San Antonio Express-News presents a series of posts on energy and transportation relating to a proposed light rail system -- contrasting San Antonio's development and transportation patterns with those of Portland, Ore. San Antonio formed a transportation task force in June 2008 to ensure mobility in the face of rising energy costs.

The commissioners of McDowell County in North Carolina have voted to purchase a diesel storage tank, in order to save money on fuel costs and be prepared for future shortages. They already have a similar tank for gasoline, but emergency services and waste collection vehicles require diesel.

Students of all ages are heading back to school this month. Post Carbon Cities Program Manager Daniel Lerch looks at what energy and climate uncertainty means for schools -- and what schools can do for the communities they serve.

As energy technologies evolve, their relationship to their surroundings also changes. Recently, attention has shifted to decentralized supplies and the effects of transportation, land use, and buildings on energy demand. It is time for planners to pay attention to the new spatial structure of energy systems. This article lays out some approaches planners could use to be more effective.

A panel of national and state experts focused on the role of transportation in a future marked by steeply rising energy costs, global warming and economic uncertainties at a "Transportation 2035" symposium on June 26, sponsored by the North Jersey Transportation Planning Authority (NJTPA). Daniel Lerch was among the panel speakers.

BYPAD (Bicycle policy audit) is an instrument for evaluating local and regional cycling policy and improvement of its quality. BYPAD has been developed, applied and continuously improved since 1999, with support from the European Commission. Meanwhile more than 100 cities and regions in 20 European countries are evaluating and improving their cycling policy, supervised by 34 certified auditors from these countries. BYPAD has become a European quality standard for cycling policy and a vital European network.

A Southeast Portland (Ore.) proposed district heating system could be a proof of concept for retrofitting neighborhoods with more efficient locally generated heat and power systems. It just needs some help from the city to move forward.

An unprecedented cutback in driving is slashing the funds available to rebuild the nation's aging highway system and expand mass-transit options, underscoring the economic impact of high gasoline prices. The resulting financial strain is touching off a political battle over government priorities in a new era of expensive oil.
