The future of energy

 




The future of energy is looking greener. Moving into 2023, drivers for renewable growth are some of the strongest the industry has seen, including competitive costs, supportive policies, and burgeoning demand.


By 2024, almost 33 percent of the world’s electricity is forecast to come from renewables, with solar photovoltaic (PV) accounting for nearly 60 percent (or at least 697 gigawatts) of expected growth, according to Renewables 2019, a report from the International Energy Agency published in November 2019. Onshore wind (309 GW), hydropower (121 GW), offshore wind (43 GW), and bioenergy follow (41 GW).


Drastically lower production costs, growing concern around climate change, evolving global energy policies, and increased pressure from investors on companies to adopt environmental social governance (ESG) policies are pushing renewables into the mainstream.


This year alone, more than 12 large U.S. coal companies had filed for bankruptcy as of October 2019, in a signal of the shifting landscape. In Australia, the National Electricity Market showed that on Nov. 6, renewables reached a milestone—powering 50 percent of the country’s main electricity grid. Rooftop solar provided nearly 24 percent, followed by wind (about 16 percent), large-scale solar (about 9 percent), and hydro (about 2 percent). While renewable energy costs may continue to rise temporarily in 2023 due to ongoing supply chain challenges, wind and solar will likely remain the cheapest energy sources in most areas, as fuel costs for a conventional generation have been rising faster than renewable costs.

Federal clean energy policies. Among other supportive provisions, the IRA extends wind and solar tax credits for projects that begin construction before 2025 and technology-neutral credits through at least 2032. Projections suggest the law will spur 525 to 550 GW of new US utility-scale clean power by 2030.

State clean energy policies. Twenty-two states and the District of Columbia are targeting 100% renewable energy or 100% carbon-free electricity, often through clean and renewable energy mandates and incentives, with target dates between 2040 and 2050.

Utility decarbonization. As of October 2022, 43 of the 45 largest US investor-owned utilities have committed to reducing their carbon emissions, and boosting renewables are one of their key strategies for meeting those commitments.

Corporate renewable procurement. With a record 11 GW of US clean energy installations in 2021, the US is set to exceed that in 2022. More than 380 global businesses have committed to 100% clean electricity by joining the RE100 renewable electricity initiative, up from about 200 in 2019.




In Germany, a Norwegian company is running one of Europe’s largest power generation facilities—and doing it virtually, in an innovative example of how the sector could overcome challenges that arise when there's little wind or sun to generate power. The plant, which according to CNN Business could power 5 million homes, uses a cloud-based artificial intelligence program to link more than

1,500 wind, solar, and hydropower plants across the continent with electricity generation and storage facilities like batteries.


Renewables were the more sustainable—if more expensive—option. By 2023, they will actually make good business sense.


In 2023: The Near Future of Renewables, we present our predictions for how the sector will reimagine itself by capitalizing on this scalable green wave.

 

1. The future of solar is bright - Although slowed slightly by geopolitical tension and trade uncertainty, solar capacity will continue to grow over the next several years—surpassing a terawatt of global solar power generation by 2023. 


2. Storage takes center stage - Storage will take its rightful place as a key grid asset by 2023, helping to increase the reliability and resilience of increasingly decentralized power systems. The adoption of diverse energy storage solutions, including long-duration batteries for utility-scale renewable integration, will grow by at least 30 percent year-over-year leading up to 2023.


3. No headwinds for wind power - Wind power will continue to grow, with increased storage capabilities explicitly developed for on and offshore wind, helping to improve the economics and productivity of such projects. Half of the 2023 global investments in the wind will go towards offshore technology and projects. 


4. The energy convergence continues - Natural resources companies, from mining to oil and gas, will continue to invest in clean or renewable energy technology, including carbon capture, utilization, and sequestration—both to diversify their portfolios and reduce their corporate carbon footprints. By 2023, 20 oil and gas majors will have joined the Oil and Gas Climate Initiative, up from 13.


5. Cleantech investments soar - Following a cycle of disappointing returns, private equity and venture capital will return to the cleantech space in full force. Whether called cleantech or climate tech, the regulatory, economic, and scientific impetus for these technologies will see $600 billion dollars in global private investment by 2023.




Overall, as the industry heads into 2023, increasing demand and enticing, long-term incentives are creating strong stimuli. Of course, the uneven economy right now poses some rough sailing, but the destination is in sight and achievable. Citizens want more solar. Residential solar demand is growing faster than ever, up 35% in H1 2022 year over year, as households react to rising retail electricity prices and weather-driven power outages.

The private sector takes notice. Private investment in renewables hit a record high of $10 billion in the past year. That could continue, as investors are attracted by transparent returns on mature technologies backed by 10-year tax credits with direct payment options.

Komasacija poljoprivrednog zemljišta

 



Komasacija poljoprivrednog zemljišta

Komasacijom se male i usitnjene površine poljoprivrednog zemljišta sjedinjuju u veće. Vlasnici i posjednici zemljišta neće snositi troškove postupka

Komasacija je skup administrativnih i tehničkih postupaka kojima se male i usitnjene površine poljoprivrednog zemljišta sjedinjuju u veće, uređuju putne i kanalske mreže te sređuju vlasnički i drugi stvarnopravni odnosi na zemljištu.

Zakonom o komasaciji poljoprivrednog zemljišta uređuju se načela za diobu komasacijske gromade, postupak za provođenje komasacije, troškovi komasacije, upravni nadzor te prekršajne odredbe.

Donošenjem Zakona o komasaciji poljoprivrednog zemljišta i provođenjem postupka komasacije omogućeno je okrupnjavanje posjeda i katastarskih čestica poljoprivrednog zemljišta, uređenje putne i kanalske mreže te sređivanje vlasničkih i drugih stvarnopravnih odnosa na zemljištu, radi njegovoga ekonomičnijeg iskorištavanja te stvaranja povoljnijih uvjeta za razvoj poljoprivredne proizvodnje.
 

Provođenje komasacije

Komasacija se provodi na temelju višegodišnjih programa, koje donosi Hrvatski sabor za razdoblje od pet godina i godišnjih programa, koje donosi Vlada Republike Hrvatske. Programe izrađuje Agencija za poljoprivredno zemljište na temelju stručnih analiza o provedbi postupka komasacije, a sukladno Programima izrađuje idejne projekte komasacije za pojedinu katastarsku općinu.

Komasacija se provodi tako da svaki sudionik komasacije dobiva za zemljište obuhvaćeno komasacijom novo zemljište u što manje čestica, u jednakoj vrijednosti, uz odbitak vrijednosti zemljišta za opće potrebe i zajedničke potrebe naselja odnosno sudionika komasacije.

Za provođenje komasacije na poljoprivrednom zemljištu koje je po načinu uporabe vinograd, voćnjak, maslinik i ribnjak, komasacija se može provoditi samo ako na to pristane natpolovična većina vlasnika, a bez njihovog pristanka ako se radi o katastarskim česticama površine do 0,5 hektara.
 
Prije pokretanja postupka komasacije Agencija za poljoprivredno zemljište saziva skup vlasnika zemljišta, radi upoznavanja sa svrhom i uvjetima pod kojima se namjerava provesti komasacija.

Rješenje o pokretanju postupka komasacije donosi Agencija za poljoprivredno zemljište, uz prethodnu suglasnost Ministarstva poljoprivrede.

Za provođenje postupka komasacije propisana su sljedeća komasacijska tijela:
  • Županijsko komasacijsko povjerenstvo
  • Državno komasacijsko povjerenstvo
  • Odbor sudionika komasacije
  • Posebno povjerenstvo koje utvrđuje stvarno stanje, raspravlja odnose nastale samovlasnim zauzećem zemljišta
  • Povjerenstvo za procjenu zemljišta.

Županijsko komasacijsko povjerenstvo određuje posebnu usmenu raspravu sudionika i drugih, radi utvrđivanja površina i vrijednosti zemljišta koje se osigurava za opće potrebe i zajedničke potrebe naselja, odnosno sudionika komasacije i područja na kojima će se sudionicima komasacije dodijeliti nova zemljišta te radi utvrđivanja načela za osnivanje novih zemljišnih čestica, nakon koje izvođač stručnih geodetskih poslova izrađuje prijedlog diobe komasacijske gromade. Nakon toga se održava usmena raspravu o nadiobi zemljišta, na koju se pozivaju svi sudionici komasacije i druge stranke koje sudjeluju u postupku komasacije.

Županijsko komasacijsko povjerenstvo donosi i izvršava rješenje o komasaciji.
 
Utvrđena je novčana kazna za sprječavanje uvođenja sudionika komasacije u posjed zemljišta koja su im dodijeljena i predložen je način rješavanja započetih, a nedovršenih postupaka komasacije prije stupanja na snagu ovoga Zakona.
 

Troškovi komasacije

Vlasnici i posjednici poljoprivrednog zemljišta neće snositi troškove postupka komasacije poljoprivrednog zemljišta. Sredstva potrebna za izvršenje višegodišnjih i godišnjih programa osiguravaju se u državnome proračunu Republike Hrvatske, proračunu jedinica lokalne i područne (regionalne) samouprave, iz sredstava fondova Europske unije (program ruralnog razvoja), sredstava donacija, te drugih sredstava zainteresiranih pravnih i fizičkih osoba.
 
Troškovi komasacijskih operacija osiguravat će se iz dva izvora i to:
  • sredstava Europskog fonda za ruralni razvoj u okviru kojeg je u Programu ruralnog razvoja mjerom - Potpora za ulaganja u infrastrukturu vezano uz razvoj, modernizaciju i prilagodbu poljoprivrede i šumarstva, predviđena potpora jedinicama lokalne i područne (regionalne) samouprave u provođenju mjera komasacije poljoprivrednog zemljišta
  • državnog proračuna Republike Hrvatske. 





Zaključak 

Stvorit će se uvjeti da sektor proizvodnje hrane, uključujući poljoprivredu, ribarstvo i akvakulturu, proizvodnju kvalitetne hrane uz održivo upravljanje prirodnim resursima i bolje upravljanje rizicima od klimatskih promjena. Produktivnost rada u poljoprivredi danas je na oko 20 % od EU-15 prosjeka, dok je produktivnost poljoprivrednog zemljišta na razini oko 50 % u usporedbi s EU-27. Hrvatska bilježi vanjskotrgovinski deficit u gotovo svim poljoprivrednim proizvodima osim žitarica i uljarica, a u trgovini ribom suficit. Niska produktivnost poljoprivredne proizvodnje povezana je s malom prosječnom veličinom poljoprivrednih površina i rascjepkanošću. Donošenjem novog Zakona o komasaciji poljoprivrednog zemljišta pokrenut će se rješavanje problema rascjepkanosti zemljišta, a time i razvoja ruralnog prostora. Veća očuvanost tla i okoliša u Hrvatskoj u usporedbi s prosjekom EU je prilika za rast hrvatske poljoprivrede. Razvoj „pametnih sela” uključivat će investicije u javnu infrastrukturu i usluge uključujući i širokopojasni internet.

Waves to Water Prize


U.S. Department of Energy (DOE) officially opened the first stage of the Waves to Water Prize, which seeks to accelerate the development of wave energy powered desalination systems and launch novel technologies to address critical water security challenges. The prize is divided into four stages, and the first concept stage is now open for applications through September 11, 2019.  
“The start of the Waves to Water Prize marks an important step toward driving growth and progress in the marine energy sector as well as spurring innovation to develop desalinization technologies that will have a global impact,” said U.S. Under Secretary of Energy Mark W. Menezes. “Supplying potable drinking water is a significant challenge in many parts of the world, and we have the opportunity to use the power of competition to find lasting solutions through the development of these two industries.”
The Waves to Water prize will offer competitors up to $2.5 million in prizes for winners to advance their solutions from concept, to technical design, to the building of a prototype, and culminate in an open water testing competition, where the systems will produce clean water using only waves as power sources. The initial concept stage has $200,000 in prizes, with up to $10,000 in funding for up to 20 winners. DOE is seeking interdisciplinary solutions that are modular and easily transportable, and ultimately can serve the clean water needs of remote communities or aid in disaster relief scenarios. More information on specific guidelines for submissions and rules of the competition can be found here.
The prize is the first to be launched by DOE under the White House-initiated Water Security Grand Challenge – a DOE-led framework to advance transformational technology and innovation to meet the global need for safe, secure, and affordable water.
The Waves to Water Prize is led by the EERE Water Power Technologies Office and administered by the National Renewable Energy Laboratory on the American Made Challenges platform. This prize builds on the success of DOE’s Wave Energy Prize, which catalyzed the development of technologies that doubled the energy captured from ocean waves.
The Water Security Grand Challenge is a White House initiated, U.S. Department of Energy led framework to advance transformational technology and innovation to meet the global need for safe, secure, and affordable water. Using a coordinated suite of prizes, competitions, early-stage research and development, and other programs, the Grand Challenge has set the following goals for the United States to reach by 2030:
Goal 1: Launch desalinaton technologies that deliver cost-competitive clean water
BACKGROUND – Over the next 10 years, 40 states expect water shortages in some areas. Cost-competitive desalination technologies can address water security and alleviate water stress by expanding alternative water resources, such as seawater, estuaries, brackish groundwater, and other sources.
CHALLENGE – Current technologies are energy intensive, with energy costs up to 10 times that of treating freshwater. Environmental issues, such as brine disposal, also pose a challenge.
OBJECTIVE – The Water Security Grand Challenge aims to address these barriers by accelerating research, development and deployment to decrease the cost of processed water, increase water supply resilience, and increase the access to low-cost water.  
Current and Recent Opportunities:

Goal 2: Transform the energy sector’s produced water from a waste to a resource
BACKGROUND – Produced water is a byproduct of oil and natural gas extraction, uranium mining, and carbon capture, utilization, and storage. In 2012, an estimated 21.2 billion barrels of produced water from oil and gas were generated in the United States.
CHALLENGE – The high cost of removing constituents specific to produced water can make it cheaper to dispose produced water than treat it. Even so, current disposal practices in oil and gas cost about $40 billion annually.
OBJECTIVE – The Water Security Grand Challenge aims to accelerate research, development and deployment of cost-effective treatment of produced water that can address water scarcity in water-stressed regions by creating alternative water sources for agricultural use, mineral extraction and processing, and other industrial operations, while creating new revenue for the extraction industry through water sales. 
Current and Recent Opportunities:
Fracking equipment in a field at daytime.
Goal 3: Achieve near-zero water impact for new thermoelectric power plants, and significantly lower freshwater use intensity within the existing fleet
BACKGROUND – Thermoelectric power plants utilize large volumes of freshwater for cooling operations. This water use accounts for about 40% of water withdrawals in the United States. Effluent water from thermoelectric power plants that is returned to its source can affect aquatic ecosystems if altering natural water temperatures and flows. Water that evaporates and is not returned to its source is considered consumed; this accounts for about 3% of U.S. water consumption.
CHALLENGE – The thermoelectric power sector’s reliance on water poses a risk in light of anticipated warming ambient temperatures, increased water stress, and more frequent extreme events like droughts. If improperly managed, the water demand of the thermoelectric power sector may limit water available to other uses, limiting economic growth of surrounding communities.
OBJECTIVE – The Water Security Grand Challenge aims to accelerate research, development and deployment of new technologies that lead to near-zero water impacts for newly built thermoelectric power plants along with significantly lower freshwater use intensity for existing thermoelectric power plants. 
Current and Recent Opportunities:
Steam emerges from three powerplant stacks.
Goal 4: Double resource recovery from municipal wastewater
BACKGROUND – Wastewater treatment plants purchase about $2 billion of electricity each year and face more than $200 billion in future capital investment needs to meet water quality objectives. This can constrain municipal budgets. For example, energy consumption at wastewater treatment plants can account for a third or more of municipal energy bills. Wastewater treatment plants can address these challenges by recovering critical resources and turning them into marketable products. This can create new revenue streams for upgrading water treatment infrastructure, particularly in rural communities, prevent nutrient pollution, and provide new sources of alternative water supplies. Recovered resources include energy that can be used on-site or sold, nutrients, such as phosphorous and nitrogen that can be used as fertilizer, and clean water that can be reused for agricultural, industrial, and potable purposes.
CHALLENGE – Energy costs are expected to increase over time and affect affordability of water for businesses and consumers. Disposal of residual biosolids from water treatment is another significant cost for municipalities.
OBJECTIVE – The Water Security Grand Challenge aims to pursue research, development, deployment and other opportunities to increase resource recovery. 
Current and Recent Opportunities:

Goal 5: Develop small, modular energy-water systems for urban, rural, tribal, national security, and disaster response settings
BACKGROUND – Small, modular energy and water systems have the potential to cost-effectively serve areas where energy and clean water are expensive and challenging to produce. Small, decentralized energy-water systems can also play an important role in serving the more than one billion people worldwide that currently lack access to reliable sources of electricity and water.
CHALLENGE – The ability to cost-effectively produce clean water for urban settings where population growth is occurring but central energy or water systems are nearing maximum capacity; for rural communities, including tribal regions where population levels cannot accommodate the economies of scale needed to make large systems viable; for military sites in remote areas without access to central electricity and water systems; and in areas impacted by disaster when storms and other events have knocked existing energy and water systems offline.
OBJECTIVE – The Water Security Grand Challenge aims to spur innovation needed to improve the cost-effectiveness of small, modular linked energy-water systems and test their performance for a range of applications.
Current and Recent Opportunities:

Renewable energy today

Renewable energy today




Renewable Energy Now.

Environmental awareness is increasing, and according to a study carried out in late 2018, 73% of the United States thinks climate change is happening, while 62% of the country believes it is human caused. Electricity production across the world is undergoing change, and more investment is being made in innovation, manufacturing, and applications for clean-energy solutions.

According to the U.S. Energy Information Administration, electricity generation in the United States in 2018 was 63.5% from fossil fuels, 19.3% from nuclear energy, and 17.1% from renewable energy sources. Among renewable energy, the main sources were 7% hydropower, 6.6% wind, and 1.6% solar power. Of fossil fuels, natural gas was at a record high of 35%, while coal saw an all-time post-WW2 record low of 27% in 2018.

The United States is currently one of the top three countries in the world in wind turbine production. There were one million solar installations in the United States in 2016, and this is expected to rise to two million in early 2019 and to four million solar installations by 2023. Both technologies are projected to grow and become more prevalent in U.S. electricity generation in the near future. The U.S. Department of Energy foresees a 10% increase in generation by solar power and a 12% increase in generation by wind power in 2019.  



There are three trends likely to impact the growth of renewable energy in the United States in 2019:

Emerging federal, state, and local political support: New local, state, and federal initiatives are receiving more attention and support. For instance, Hawaii and California have set the goal of 100% renewable energy by 2045, while over 200 mayors in the United States have established the objective of 100% renewable by 2035. New policies are expected to trigger further growth in wind and solar power.
Increase in investment: By the end of 2018, 156 global corporations — many based in the United States — have committed themselves to 100% renewable energy. Corporate procurement continues to increase, and asset management companies are collecting renewable energy portfolios. One example is Goldman Sachs, which has acquired 76 solar energy projects found on 143 sites. Investment in renewable energy in the United States exceeded $40 billion in both 2017 and 2018, and total private investment in renewable energy could reach a cumulative $1 trillion between 2018 and 2030.
Investment in technology is also on the rise, with advancements in technology bringing costs down. Research on solar and wind power are areas of interest, with more research via government investment on the horizon. The U.S. Office of Energy Efficiency and Renewable Energy budget was increased by 2% for 2019 to reach $2.38 billion by Congress.

Emerging policies, advancements in technology, increases in investment, and more social awareness will most likely cause an increase in renewable energy growth in 2019 in the United States. The decrease in renewable energy costs, in addition to favorable federal policies, are also likely to stimulate renewable demand.



In G20 countries, energy generation by fossil fuels costs between $0.05 and $0.17 per kilowatt-hour today. Renewable energy is expected to cost $0.03-$0.10 per kilowatt-hour by 2020, while the price of onshore wind power and solar photovoltaic projects could be as low as $0.03 per kilowatt-hour by 2019.

Renewable energy demand will expand opportunities; and although there is some political resistance, the general trend in the United States and worldwide is towards sustainability and renewable energy growth.

The decade-long trend of strong growth in renewable energy capacity continued in 2018 with global additions of 171 gigawatts (GW), according to new data released by the International Renewable Energy Agency (IRENA) today. The annual increase of 7.9 per cent was bolstered by new additions from solar and wind energy, which accounted for 84 per cent of the growth. A third of global power capacity is now based on renewable energy.  

IRENA’s annual Renewable Capacity Statistics 2019, the most comprehensive, up-to-date and accessible figures on renewable energy capacity indicates  growth in all regions of the world, although at varying speeds. While Asia accounted for 61 per cent of total new renewable energy installations and grew installed renewables capacity by 11.4 per cent, growth was fastest in Oceania that witnessed a 17.7 per cent rise in 2018. Africa’s 8.4 per cent growth put it in third place just behind Asia. Nearly two-thirds of all new power generation capacity added in 2018 was from renewables, led by emerging and developing economies.



“Through its compelling business case, renewable energy has established itself as the technology of choice for new power generation capacity,” said IRENA Director-General Adnan Z. Amin. “The strong growth in 2018 continues the remarkable trend of the last five years, which reflects an ongoing shift towards renewable power as the driver of global energy transformation.

“Renewable energy deployment needs to grow even faster, however, to ensure that we can achieve the global climate objectives and Sustainable Development Goals,” continued Mr. Amin. “Countries taking full advantage of their renewables potential will benefit from a host of socioeconomic benefits in addition to decarbonising their economies.”  

IRENA’s analysis also compared the growth in generation capacity of renewables versus non-renewable energy, mainly fossil-fuels and nuclear. While non-renewable generation capacity has decreased in Europe, North America and Oceania by about 85 GW since 2010, it has increased in both Asia and the Middle East over the same period. Since 2000, non-renewable generation capacity has expanded by about 115 GW per year (on average), with no discernible trend upwards or downwards.



Hydropower: Growth in hydro continued to slow in 2018, with only China adding a significant amount of new capacity in 2018 (+8.5 GW).

Wind energy: Global wind energy capacity increased by 49 GW in 2018. China and the USA continued to account for the greatest share of wind energy expansion, with increases of 20 GW and 7 GW respectively. Other countries expanding by more than 1 GW were: Brazil; France; Germany; India; and the UK.

Bioenergy: Three countries accounted for over half of the relatively low level of bioenergy capacity expansion in 2018. China increased capacity by 2 GW and India by 700 MW. Capacity also increased in the UK by 900 MW.

Solar energy: Solar energy capacity increased by 94 GW last year (+ 24 per cent). Asia continued to dominate global growth with a 64 GW increase (about 70% of the global expansion in 2018). Maintaining the trend from last year, China, India, Japan and Republic of Korea accounted for most of this. Other major increases were in the USA (+8.4 GW), Australia (+3.8 GW) and Germany (+3.6 GW). Other countries with significant expansions in 2018 included: Brazil; Egypt; Pakistan; Mexico, Turkey and the Netherlands.

Geothermal energy: Geothermal energy increased by 539 MW in 2018, with most of the expansion taking place in Turkey (+219 MW) and Indonesia (+137 MW), followed by the USA, Mexico and New Zealand.



Globally, total renewable energy generation capacity reached 2,351 GW at the end of last year – around a third of total installed electricity capacity. Hydropower accounts for the largest share with an installed capacity of 1 172 GW – around half of the total. Wind and solar energy account for most of the remainder with capacities of 564 GW and 480 GW respectively. Other renewables included 121 GW of bioenergy, 13 GW of geothermal energy and 500 MW of marine energy (tide, wave and ocean energy).
