Unfortunately, neither energy efficiency nor renewable fuels are a panacea for all the security risks posed by energy-spurred climate change, air pollution, and water scarcity. Physical constraints—such as the lack of available transmission capacity to connect renewables to the grid and the lack of pipeline capacity to bring rural sources of biofuels to urban markets—present barriers to widespread implementation. Varied challenges, such as intermittency and relatively high conventional costs, also inhibit renewable energy development. Political, financial, and regulatory uncertainties also delay both energy efficiency and renewable energy deployment. These obstacles are significant, but not insurmountable. Without a doubt, both renewable energy and energy efficiency are necessary and vital components of the solution to the environmental security problems caused by the expanding energy needs of developed and developing nations.
Agriculture sector modernization and renewable energy development

Even though the subsidy cost per unit of energy produced is expected to decline, most renewable energy sources will need continued support in order to compete in energy markets. While remaining costly in the beginning until the emergence of mass production and cost reduction, the renewable energy development is expected to bring long-term benefits of both increased energy security and independence, and greater climate and environmental protection. Market launching and penetration that leads to mass production and significant cost reduction will be the key factors for renewable energy development in the next decades, which will make renewable technologies cost-competitive or cheaper than fossil energy technologies.

Sustainable energy development yields beneficial environmental impacts and in the long term reduces energy costs. In contrast to green power or electricity generated from renewable sources, brown power is electricity generated from environmentally hostile technologies. Investing in green power sources in lieu of brown power is one of the most effective ways to reduce atmospheric green house gases (GHGs). Global investment in renewable power capacity was more than double the dollar allocations to new coal and gas generation, which was estimated to be $130 billion in 2015 [3].

Morocco presently became interested in renewable energies. The use of these renewable sources is the most valuable solution to reduce the environmental problems associated with fossil-based fuel energy generation and achieve sustainable and clean energy development. Hydropower, wind, biomass, solar and geothermal are the most important renewable sources for energy generation (Panwar, Kaushik, and Kothari 2011). Solar energy is attributed as one of the most promising renewable energy (RE) alternatives (Ouammi et al. 2012). In particular, solar photovoltaic (PV) energy is one of the RE sources with the greatest potential worldwide (Pringle, Handler, and Pearce 2017; Wadhawan and Pearce 2017).

Nowadays, governments worldwide are confined to the usage of fossil fuels which are emitting more harmful emissions to nature. Diminution of emissions is the foremost challenge for the world now. In this regard, detailed research is incredibly much indispensable to control these harmful emissions in the country. In this direction, some novel approaches that curbs fossil fuel dependency and environmental degradation play an imperative role in alternative fuels and their utilisation in engineering applications. The fossil fuel applications for energy development in sectors such as domestic, transportation and industrial , cause serious issues on the environment as they are the main key sources to produce harmful emissions to nature. Thus, it leads to global warming and ozone layer depletion, causing adverse effects on mankind. In this regard, the search for alternate solutions in energy development and conversion is highly pronounced. Continuous and sustainable development of various technologies for utilising renewable energy sources is noteworthy for the future of a balanced global energy economy. Many researchers have put their sincere efforts into improving the efficiency of the solar water heating system. Still, we are unable to use 100% solar energy because of the various losses in the solar system. Many researchers have conducted experiments on thermosyphon or forced circulations hot water systems with and without nanofluid applications. However, few investigations were made on the solar water heating system with nano-coatings on the reflective plate placed at the bottom of the array of evacuated tubes. Therefore, in this current study, a sincere effort is made to unfold the effect of Magnesium Oxide (MgO) nanoparticles (which are prepared in-house and characterised) on the performance of the solar water heating system.
Developing a cost-efficient dual sampling system for lot disposition by considering process yield and quality loss

Renewable energy is an essential step toward sustainable energy development against global warming and urban heat issues (Masson et al. 2014). Solar panels have become an increasingly popular form of alternative energy worldwide, using photovoltaic and Si solar cells to convert radiation into electricity. Many practical applications of using solar panels as a power source include residence electricity consumption, transportation system, irrigation in agriculture industries, refrigerating medical supplies for health care, and installation of infrastructure for public use.
