Solar Hot Water: Which is better, PV or Thermal?

Recently, reductions in solar electric (PV) costs and maturation of air-to-water heat pump technology have provided a new model: solar-electric assisted heat pump water heating (HPWH).

Can the Challenges of Desert Solar be Overcome?

The most significant engineering challenges facing desert solar are windblown sand, lack of water and transmission lines. Aside from the physical logistics, political resistance also hinders the development of desert solar.

Solving Turbine Wake Issues in Dense Development Areas

Using a specialized wake model, 3TIER is able to help clients take into account the impact of external wakes on the final net energy numbers they must take to their project stakeholders and financing partners.

Critical thinking for innovation at the World Energy Congress 2013

For most energy and utility companies, success will be achieved through transforming the utility network, improving generation performance, and transforming customer operations - via big data analytics.

Real World PV Solar Project - One Year Later

We've been living with the solar system for a little over a year now and I thought it time to report back to you about the experiences we've had and talk about how the system is operating and performing.

DC Fast Chargers for Electric Cars

DC Fast Chargers can charge an EV battery in 15 - 30 minutes, depending on vehicle make, model and initial battery state-of-charge.

Flywheels: A Way To Change the Utility Business Model?

The purpose of this note is to explore the feasibility and stimulate discussion of such an approach ( a few others have discussed this possibility as well), which has the potential to reduce utility peak power demands, reduce consumer costs by taking consumers off the grid at peak periods, and transform the nature of utilities.

Solving Wind Farm Siting

An automated approach takes the guesswork out of siting. Software-generated algorithms automatically search the solution space, quickly and efficiently providing planners with a near optimal solution that can statistically be guaranteed.

The Solar Renewable Energy Credit (SREC) Program

A Solar Renewable Energy Credit, often referred to as an SREC, represents the renewable component of 1 megawatt hour of power production generated from a solar photovoltaic system.

Financing - The single largest roadblock for energy-saving projects

It's not surprising that CFOs are a little nervous about investing hundreds of thousands of unbudgeted dollars in projects with hard-to-believe savings estimates. Unfortunately, this industry is somewhat a victim of its success - the better the products, the harder the estimates are to believed.

4 Reasons Your Next Vehicle Will Be Solar Powered

Advancements in battery technology and recharging capabilities will drive adoption. Since the beginning of 2013 we have not only seen fast-charging stations that rapidly refill a battery but also wireless recharging capabilities and battery swap techniques.

Renewable Energy Vital for First Nation and Remote Communities

Some First Nation communities have initiated solar and wind power and mini hydroelectric initiatives but more needs to be done to ensure that all remote communities have access to clean and affordable energy.

Cutting Consumption, Saving Lives: Fuel Cell Technology Proves Powerful in Demo

The Solid-Oxide Fuel Cell Tactical Electrical Power Unit is aimed at reducing the need to transport fuel around the battlefield, especially in dangerous theaters like Afghanistan, where enemies routinely target supply routes with homemade bombs.

Shaw Lynds, Senior Research at Maxwell Technologies, Inc Explains Ultracapacitors

In general, ultracapacitors are great solutions whenever the power demand is high, but the duration is short. For example, we are expanding into the diesel truck market, where the high power demand of engine starting can place a great strain on the batteries, greatly lowering their useful life.

IBM's Hybrid Renewable Energy Forecaster

The Hybrid Renewable Energy Forecasting (HyREF) solution combines big data analytics and weather modeling technology to accurately forecast the availability of wind power and solar energy.
