“…In 2017, indirect carbon emissions recorded electricity consumption in the electricity sector fell by 3.5% [40]. Two primary factors, in particular, have contributed to reducing the carbon intensity of electricity generation (CO 2 /kWh) since 2005-replacing coal with lower carbon dioxide emissions and more efficient combined natural gas production and increasing non-carbon dioxide emissions [41,42].…”

Renewable energy sources (RES) are gradually becoming one of the key elements in the process of achieving energy efficiency worldwide. This trend can be observed in many developed Western economies—for example, in the United States, as well as in the United Kingdom. Hence, the role of innovative policies for promoting energy efficiency is becoming crucial in transition to the post-carbon economy. The shift to the carbon-free future make all actors to face forgoing commitments Nevertheless, customers and residential households are the first and the most important players in the pursuit of the energy-efficient future. Without them, carbon-free economy based on RES would never take the shape as envisaged. Our paper focuses on the innovative strategies and policies studying the effect and the scope of RES penetration into the households. We employ and empirical analysis of the effects from using RES in households using an example of the residential households in the northwest region of the United Kingdom (UK) with and without solar photovoltaic (PV) panels and electric vehicles (EV). We analyse the four scenarios that are aimed at analysing the system dynamics and providing differentiation between systems in terms of the varying values of the gross demand, tariffs, metered import, and the total revenue. Our results demonstrate that the solar PV leads to the transfer of costs and wealth regardless of the ownership of PV and EVs. Solar energy generation reduces the share of UK solar PV households per kWh costs of the distribution system which causes the augmenting of the per unit charges as well as to the changes in payments for the electricity that impoverishes less wealthy customer groups. It also becomes clear that with the increase of EV penetration, the existing energy efficiency schemes would have to be revised.

“…The majority of the energy used in transport comes from conventional fuels [15,16]. This situation is gradually beginning to change through the introduction of alternative fuels and the promotion of electromobility [17,18]. Within the meaning of the Directive [19], alternative fuels are fuels or energy sources which serve, at least in part, as a substitute for energy sources in the transport from crude oil and which have the potential to contribute to reducing the dependence of EU member states on oil imports and to decarbonize transport and improve the environmental performance of this sector.…”

The Effects of Pressure and Temperature on the Process of Auto-Ignition and Combustion of Rape Oil and Its Mixtures

The effects of initial pressure and temperature in a constant volume test chamber with a common rail injection system on the processes of self-ignition and combustion of rapeseed oil and various blends of rapeseed oil with diesel oil are explored. Based on the obtained pressure waveforms the amount of emitted heat was determined, and the tested fuels were compared. The variations of a number of physicochemical characteristics that occur during the combustion processes were evaluated for several mixtures of fuel components. It was found that in the case of blends of rapeseed oil with diesel oil, the best results were obtained for a mixture containing 70 weight percent of diesel oil and 30% of rapeseed oil.

“…Road transport has been considered for many years as one of the main emitters of substances that impair the quality of atmospheric air [13,14]. About 30% of total CO 2 emissions in the EU come from the transport sector, of which 72% from road transport [15][16][17]. There are two ways to reduce CO 2 emissions from cars: Increasing vehicle efficiency or changing the fuel used [18][19][20].…”

An increase of needs for replacement of fossil fuels, and for mitigation of Carbon Dioxide emissions generated from fossil fuels inspires the search for new fuels based on renewable biological resources. It would be convenient if the biological component of the fuel required as little as possible conversion operations in the production. The obvious response is an attempt to use unconverted, neat plant oils as a fuel for Diesel engines. The present paper is devoted to the experimental studies of the combustion process of neat rapeseed oil, and its mixtures with gasoline and ethanol as additional components of the mixtures. The investigation of combustion was carried out in a fixed volume combustion chamber equipped with a Common Rail injection system. It is shown that the instant of ignition, as well as time-dependence of heat emanation, are strongly dependent upon mixture composition. The results enable the design of mixture compositions that could serve as commercial fuel for Diesel engines. Such fuels are expected to fulfill the requirements for the sustainability of road transport.
