At present, the national scenario presents clearly defined goals, reducing emissions of "diffuse sectors" by 26% and industry by 43%. Reaching these renewable objectives planned for Spain also has a clear deadline, 2030. However, we find that the fundamental thing is still pending to be determined, we are talking about the "how", that is, the concrete actions and measures that are going to be put in place in Spain to have fulfilled our environmental commitment before the arrival of the European Commission deadline.
For the moment regarding the reduction of emissions in the diffuse sectors, those not subject to emissions trading, we are really advanced as a result of the crisis. As a result of the bad economy, for example, the car was no longer used in favor of public transport, now what is worth asking is whether we will lose what we gained at the start. On the other hand, regarding industry emissions we can not be so optimistic, since in 2014 and 2015, far from reducing emissions, Spain increased them by 1.7% and 10% respectively.
In the following map we can see the evolution of Spain with respect to other countries of the European Union until 2015.

In order to face a situation of apparent blockage and lack of action, agents in the biomass sector strive to highlight the wealth of our country in terms of resources that can be harnessed energetically.
With the new Law on Climate Change and Energy Transition, it is expected that biomass and waste will be contemplated in a real and practical way, as means for the generation of clean electric power. The technologies are already on the market and are fully developed, waiting, as we pointed out, to be considered as a solid alternative. Betting on models of electricity generation with biomass or waste, such as the generation of electricity through ORC (Organic Rankine Cycle) or the generation of electricity with steam, it is possible not only to have the electricity necessary for self-consumption, but also to have an excess energy that can be discharged into the electricity grid. Both models, both ORC and steam, are sustainable and valid power generation systems for the development of hybrid energy models based on renewable energy.
Despite the advanced state of maturation and innumerable advantages that renewable energies already offer, it is necessary to continue advancing in their development, looking for ways to continue increasing their efficiency. The hybrid and renewable energy models are an alternative for improvement, because thanks to the different nature and characteristics of the resources used, generating synergies and providing greater value.
Located within this framework, we find a booming alternative which is the combination of electric power generation systems using ORC or steam, both using biomass or waste as fuel, with solar or wind power plants.
Until now, energy auctions have been carried out according to price criteria, instead of on the basis of a complete study on the advantages and benefits provided by each of the renewable technologies. This situation has only encouraged the development of large infrastructures and power plants, mainly wind and solar. It is true that they have also started up electricity with biomass, but they are still a minority.
Within this scenario, the least benefited have been the small and medium size biomass plants, which present valuable social benefits at a local level that are rarely taken into account in said auctions and distributions.
By consolidating an extensive network of small local biomass power plants, it would be possible not only to achieve greater national independence of fossil fuels and external supply, but also to enrich localities in a distributed manner, since biomass, in addition to being a renewable resource, is a social resource capable of generating employment and contributing to the circular economy.
