Nuclear, solar, and smart grids
Nuclear power and solar power are two completely different beasts for the world of smart grid.
Nuclear power:
is produced far from the consumers, in extremely large plants, and the energy must flow on the transmission lines to get to the loads;
cannot be turned on and off whenever you want: a nuclear power plant is almost always in operation, producing a constant amount of power

Can hydrogen replace oil?
There are plenty of news, papers, magazine covers, that ask the same question: "Will hydrogen replace oil?"
The question is ill-posed, and that's why.
Hydrogen is NOT a source of energy, it's just a way to store energy for later use.
Therefore you cannot compare hydrogen and oil, you should instead compare hydrogen and batteries, for example.
Unfortunately, there is no hydrogen available in
LG Electronics invests in Smart Grid Technology
When company says that they are investing into smart grid technologies, they can be talking about very different ideas:
the smart grid architectures, standards, ideas: this is the most intriguing part, leads to patents and scholarly articles, and the big names are into it, including academia
the smart grid power electronics, to equip a smart transmission and distribution grid: transformers,
Smart Grid in South Korea
The modernization of the country's electric grid is a vital component of the Lee Myung-bak administration's comprehensive energy plan, which aims to reduce South Korea's dependence on oil, create jobs and help the nation's key industries compete successfully in the global market for clean energy technology.
South Korea plans to invest 960 billion won ($820 million) into smart grids this year.
Will lower solar costs revive Moore's law talk?
IEEE Energy Wise blog asks this interesting question.
Many know about Moore's Law for electronic devices and in particular integrated circuits or microprocessor:
"Moore's law describes a long-term trend in the history of computing hardware. The number of transistors that can be placed inexpensively on an integrated circuit has doubled approximately every two years"

Smart meter communication standards NEEDED!
With the expression "Smart Grid" one usually wants to describe the integration of information technologies (communication, computing, automation) into the world of power transmission and distribution networks.
This scenario includes a huge number of different aspects. Among them, one of the most important (and one of the first that is being developed) is the idea of smart metering.
With smart
Solar + Hydro power: winning combination?
In the realm of micro generation (residential buildings, small towns, isolated houses or cabins) you may have heard about the winning idea of combining solar power generation with hydro-electric generation.
Why is this?
It has to do with the intermittent behavior of almost all the renewable energy sources: wind, solar, waves, hydro. Unfortunately the availability of these sources of energy
TURANOR PlanetSolar
The goal of the team PlanetSolar?To complete the first world tour with a solar boat, that is an electric motor boat powered by quiet and clean energy sources, fed exclusively by the Sun.
With this project, the team wants to demonstrate that current technologies to improve energy efficiency are reliable and efficient and, secondly, to advance scientific research in the field of renewable
Organic photovoltaics: cheap? efficient?
Unlike traditional semiconductors (silicon, for example), organic PV employ carbon-based plastics, dyes, and nanostructures, and can be manufactured via a printing process: much cheaper than high temperature processing that is needed by inorganics.
Organic solar panels are also lighter, more flexible, and therefore promising for an extremely wide class of applications, from covering entire

You will hear about the latest component developments, design techniques, communications protocols, architectures, smart-grid
Solar Cars
Are solar car possible?
Forget about the cost of solar panels, the cost of batteries. Let's focus on how much power solar panels can produce and how much power solar cars need.
This is the very first step we must do, to understand if a dream like solar cars are something that we are going to see in the near future of if they are going to stay in our dreams.
Let's start from some facts: in the

Energy from wood
There is an increasing interest in new energy sources, intended to replace fossil fuels like gas and oil.
There are two main reasons why fossil fuels are to be replaced, at least in part:
they are going to end, eventually
we produce a CO2 when we use them
These two problems are quite connected, but they are different. When we talk about renewables, we usually mean solutions that satisfy both
DC voltage: 12, 24, or 48 volts?
When designing a distributed power generator (solar panels, micro wind turbines, etc.) a choice have to made: the DC voltage of the system.
In other words, the generator (panels or wind turbine) will produce DC electrical current at a given voltage, let's say 24V. A cable will carry this power to the batteries, the charge controller and to the inverter, that have to be designed for the same
Smart-Grid Carbon Savings
As IEEE Spectrum reports, the Pacific Northwest National Laboratory has issued a report in which carbon savings from introduction of smart grid technologies are estimated.
There are two main ways in which a smarter grid can reduce carbon emissions:
direct carbon savings through smart devices (meters, for examples); the estimate is that a 12% reduction is expected by 2030;
allowing renewable
Cheaper electric bill with IBM smart house devices
During the last year, IBM started a pilot study in Fayetteville, North Carolina, to find out how much can people reduce their energy consumption by using smart grids and by slightly changing their habits.
It looks like smart grids + change of habits is a winning idea: the results gathered so far show a 15% saving in energy consumption in residential areas and small businesses, with up to 40%
Power Line Communication for Smart Grids
The idea of having data flowing over power lines is not new.
For example, if the goal is to have regular Internet traffic to flow over the power distribution cables that reach your house, one can exploit the layered architecture of Internet. In other words, you can exploit the fact that communicating agents do not care about the physical mean that supports the information flows.
This great
