The EU has set ambitious targets for both the short and long term with the 2020 climate and Energy package as well as a commitment to reduce greenhouse gas emission by 80-95% by 2050. UE has set ambitious target by 2030 as well both on renewable energy production and greenhouse gas reduction.
DSR could be a crucial solution in order to get the mentioned targets because of its benefits. In fact DSR creates value for the consumers by allowing them to be rewarded for changing their consumption behaviour and therefore providing flexibility to the system operators and helping them to maintain the grid balanced. In addition DSR will also play a key role in the reduction of additional generation and proportionally enhance the role of renewables in the energy supply, thus making it more secure and reducing the risk of price spikes due to political instability in the supplier countries.
We wish you 2 kilometers of joy for a very special Christmas.
A new year rich of challenges and milestones.
A river of courage to realize your projects.
Because any of us is here to seed beauty.

When talking about SEU (Efficient Consumption Systems) it often seems like a futuristic model that will have great spread. This statement is certainly acceptable but limiting because SEU not only will develop in the near future but they also did in the past!
Let me explain better. By definition, SEU are: “systems in which a electricity production source [...], powered by renewable sources or by high efficient cogeneration [...], is directly connected, by means of a private link [...], to the system for the consumption of a single end user, also corresponding to the producer [...]”. Thus, everyone who produced energy from a photovoltaic system in the last 10 years can be considered a SEU!
Let’s try to image a world without coal fired power plants, incinerators, steelworks, cement plants, refineries, chemical plants and all those plants commonly agreed as polluting ones.
Of course we would live in cleaner and nicer world, but most probably we would also be compelled to give away most of the comforts we get used to and upon which is based our present idea of wellbeing: we would not be able to produce enough energy to meet our needs, we would live in wood made houses or caves, we would need fire to heat e we would move on foot or by horse; we would not even go by bicycle because we would need to melt metals and synthesize tires from hydrocarbons…
The European project GRID4EU aims at making demonstration on Smart Grid advance solutions for the European Union: in collaboration with Enel, Loccioni Group realized a Lithium-Ion battery Energy Storage System of 1MW/1MWh.
The Italian demonstration, addressing to Medium Voltage Network, aims at realizing an advanced control system communicating with all the network relevant nodes: MV generators, HV/MV and MV/LV substations and a storage facility.
Global demand for Data Centre (DC) capacity and Data Centre services continues to rise steadily, despite macroeconomic conditions. The DC role is expanding thanks the rapid increase in Virtualization, Cloud computing, High-Powered Computing, and the vast growth in Internet use, with the consequent increase of power consumption.
Power consumption of DCs becoming a serious concern in the design and operation, given by the need to save energy and use green energy to reduce environmental impact and energy costs. The effects of high power consumption manifest not only in the cost of electricity consumption, but also in the costs spent in designing effective cooling systems to ward off the generated heat.

“How many years can a mountain exist – before it is washed to the sea?”. This beautiful verse of Bob Dylan, taken literally, captures the essence of what we call hydrogeological risk: the territory evolution is a natural and inevitable process: it is only a matter of time. How much time?They are very long-term processes, “geologic time” as they say: that’s why we are not worried about that. But, at the detail level there can be significant evolutions even in shorter periods, ranging from a few hours to hundreds of years: a piece of slope collapse, the water floods lands that are normally dry, a river changes its course, a level ground falls or rises gradually.
More than we had imagined in the past, we are realizing that our strategies to mitigate hydrogeological risk must be able to adapt to changes: the territory will change despite of our actions and, at times, because of them; but also changes in anthropogenic pressures, our desire to use the land; and, in recent years, climate changes, that are changing the characteristics of the natural forcings. In addition to traditional defense works, inflexible by nature, it is important to increase the range of solutions by giving more importance to territorial planning, planning and emergency management, the design of structures and infrastructure less vulnerable to flooding. These actions are typically much more adaptive to changes in the system; they do not necessarily prevent the flood fulfillment but, at least, they can mitigate its effects, and, above all, avoid the loss of lives.
What is the role of technology in this? It always provides the tools and infrastructure for environmental monitoring, an essential basis for the understanding and control of the territory and of the processes that affect them. The development of the last decades allows us to measure the force and the effects in real time, providing evolutionary scenarios used for the dynamic risk management, supporting decisions in an emergency. These capabilities set new challenges in mitigating risks and require a more complex approach than the passive protection provided by a bank; in return, the technology typically requires lower investment while offering excellent adaptability to climate , territorial and social changes.
Conclusion: there are no simple answers to complex problems such as those posed by natural hazards. Or to say it in Bob Dylan style , “the answer is blowing in the wind.” Catch it is not easy.
