AHAM lists the following six key features associated with smart appliances: Dynamic electricity pricing information is delivered to the user It can respond to utility signals Integrity of its operation is maintained while automatically adjusting its operation to respond to emergency power situations and help prevent brown or blackouts The consumer can override all previously programmed selections or instructions from the Smart Grid, while ensuring the appliance‘s safety functions remain active When connected through a Home Area Network and/or controlled via a Home Energy Management system, smart appliances allow for a total home energy usage approach. This enables the consumer to develop their own energy usage profile and use the data according to how it best benefits them It incorporates features to target renewable energy by allowing for the shifting of power usage to an optimal time for renewable energy generation, i.e., when the wind is blowing or sun is shining According to a research piece written by Zpryme, the smart appliance market is projected to grow from $3.06 billion in 2011 to $15.12 billion in 2015, with the U.S. accounting for 46.6 percent of that in 2011 and 36 percent in 2015. By contrast, China is expected to have an 11.6 percent share in 2011 and an 18.2 percent share in 2015. What's more, there are some strong drivers to smart appliance investment: Pricing: Bringing smart appliances to the mainstream means aligning ecological innovation with affordability Environment: With the build-out of metering and real-time pricing, consumers will see economic and environmental incentives for reducing power consumption first hand with their smart appliances Energy efficiency: When a consumer buys an appliance, they commit to paying both the first cost and the operating cost for the life of the product. And over the existence of the appliance, the energy cost to run it could be significantly greater than the initial cost Smart grid build-out: Smart appliance growth relies heavily on how quickly smart grid infrastructure can be rolled-out and readily accessible to communities Government subsidies: Like the Cash for Appliances program in the U.S., governments could and should play an active role in furthering the smart appliance agenda

Oil plays a negligible role in power generation and therefore does not compete with renewables in this respect. Renewables have become the dominant source of new power generation capacity over the last six years because they are competitive at the bottom end of the conventional fossil fuel power generation cost range – primarily with coal.

Oil plays a much more important role in the transport sector, which accounts for half of total demand, and where without low-emission transport policies in place, an extended period of low oil prices, may impact the speed of electric vehicle adoption.

Conversely, oil price volatility may undermine the viability of unconventional oil and gas resources as well long-term contracts, providing a window of opportunity to reduce or redirect fossil fuel subsidies towards clean energy, while minimising the potential of social disruption.

Yes, "green" energy has great emotional and political appeal. But before we wrap all our hopes -- and subsidies -- in it, let's take a hard look at some common misconceptions about what "green" means.

De Spaanse regering denkt dat zij subsidies, die bedoeld zijn voor producenten van zonnestroom, op te strijken voor elektriciteit die ze ’s nachts opwekken met dieselgeneratoren.
