Global Renewable Energy Outlook

Several newly developed energy future scenarios have been developed with somewhat different results. The future is difficult to predict across all energy markets and signifi­cantly more so for renewable energy ones. Analysis requires assumptions for GDP, the policy landscape, continued environmental awareness, and the investment landscape.

In a recent report by BNEF, a “new normal” scenario is outlined with world eco­nomic growth at pre-recession levels, stronger policy coordination among major emitters, sustained investments, continued technological innovation, and strong demand for fossil fuels.[114] In this scenario, BNEF estimates that by 2030, renewable energy will make up nearly half (48%) of total power generation (up from 28% in 2012).[115] [116] Solar is expected to make up between 14% and 17% of global energy pro­duction under the various future scenarios.

This figure suggests a continued rapid expansion of solar energy. In fact, BNEF estimates that solar PV will account for 30% of all new power additions through 2030. Solar is expected to become the leading renewable source by share of market, rising to account for between 27% and 32% of all renewables by 2030.11

This rise is quite dramatic and in line with estimates that suggest rising fuel prices. BNEF also estimates that 73% of total investment in power generation will be directed to renewables, to the tune of nearly $8 trillion. About $5.5 trillion of this will be invested in solar and wind with a maximum of $3.2 trillion under the most aggressive scenario for solar alone.[117]

These long-range scenarios are fascinating, but shorter term projections have greater accuracy. Renewable energy production has grown by a 5.8% rate globally in 2010 and 2011, leading the EIA to project a growth rate for 2011-2017 that is 60% higher than 2005-2011. In its scenarios, it expects the number of countries that pro­duce solar PV to double between 2011 and 2017.[118]

Overall energy demand is clearly important for the proliferation of solar technolo­gies. Increasing global demand, concern over climate change, increasing competi­tiveness of solar economics, and strong public support have led to a massive increase of installed solar electric capacity across the globe.

EIA projects that by 2017, solar will contribute 4.9% to renewable generation. This is based on an expectation that solar PV will grow by 35 TWh per year—an increase of 27.4%—from 70 to 230 GW over the period. This growth will be led by China (32 GW), the United States, (21 GW), Germany (20 GW), Japan (20 GW), and Italy (11 GW).[119]

CSP is expected to explode over the period from 2 to 11 GW by 2017.[120] Despite this 550% growth scenario, expectations were higher and the small base tempers the excitement. Clearly, PV growth has eroded some of these gains. Nonetheless, the United States is expected to lead all nations in CSP with 4 GW added by 2017. At the same time, solar thermal heating is expected to grow by 150% over the period.[121]

These global scenarios illustrate a strong and continued demand for solar energy. A country-level analysis is also critical for determining the best markets for solar in the future.

According to the SEIA, US annual PV installations grew to an impressive 3313 MW in 2012, an increase of 76%. The new capacity represents 11% of global installations, its highest share in 15 years, and increases the US installed capacity figure by more than 100% from 2011 at 7221 MW.[122]

The residential market is booming in the United States with over 83,000 installa­tions in the sector. This is largely driven by cost; the blended average sales price for PV modules for Q4 2012 was $0.68/w, a staggering 41% below the Q4 2011 price of $1.15/W.[123] This pricing led to further reduction to the cost of PV systems and an expectation of 30% growth in 2013.[124]

The 2012 growth numbers are significant, especially given that over 39% of the capacity was installed in Q4. The market was led by California, the historical leader, as well as New Jersey, Arizona, North Carolina, and Massachusetts.

In the United States, the residential market continues to grow steadily with install­ers adding 488 MW in 2012, growth of 62% from 2011. The fastest growing residen­tial markets are California, Hawaii, Arizona, and Massachusetts. Only Pennsylvania, which suffered from renewed policy uncertainty, shrank in 2012.[125]

The nonresidential market in the United States grew 26% in 2012 adding 1043 MW of new capacity. The market leaders, California and New Jersey, both started 2012 strong but declined after midyear. This was offset by emerging growth in Massachusetts, Hawaii, Maryland, and New York.[126]

While these figures are impressive, utility growth exploded, more than doubling from 2011 at 1782 MW (more than half of the year’s installed capacity growth). The rise, however, has meant that many states have hit their renewable targets, so growth is expected to slow in most parts of the country.[127]

GTM Research projects 2013 PV capacity additions to grow by 29%, again out­pacing the global installation rate but down from 2012 impressive rate. The resulting capacity additions total 4.3 GW of PV. This is mostly lower due to slowing utility installations, and also likely to track previous years, with strong Q1 and Q4 installa­tions. The projections seem on track, with 723 MW reported to be installed in Q1 of 2013, representing 33% growth over Q1 2012.[128]

Ernst & Young and BNEF expect that public opinion, as demonstrated in the ree­lection of President Obama and recent polling, will drive the United States to con­tinue its growth in the medium term for solar energy. Americans grow wearier and wearier of reliance on foreign oil and its inevitable entanglements, and are seeking support for domestic sectors that are likely to grow jobs.[129]

The United States leads the Ernst & Young solar attractiveness index, maintaining its position in 2011 and 2012. India remains at #2, a surprising ranking for a country with an old and insufficient grid, blackouts, policy uncertainty, and other issues. However, with one-third of India’s population off the grid, and a significant energy deficit in the country, there is potential for significant growth in distributed generation.[130]

China ranks third in the indices, however, the shift towards the nation is fully underway and if current trends continue, it will easily lead the world in the near term. While solar has not taken hold as quickly as wind power, for example, but changes in policies and new investment appear to be rapidly changing the focus of the country to installed solar capacity. Much of the shift in focus is to further stimu­late the saturated PV production plants.[131]

Europe continues to fade, as it reaches near saturation in most of its markets. Germany, a perennial top nation in the index, sits at 4, while Spain has fallen to 9.[132]

Several new markets have emerged on the scene, however, predominantly in the Middle East. Specifically, the UAE and Saudi Arabia are marching ahead, both mak­ing the index for the first time in 2012 at #12 and #14, respectively.[133]

Of course, these statistics and indices are useful to analyze the markets for install­ing solar capacity, but do not address the market for production. This is because, quite frankly, over the course of time it has taken to write this text, the section high­lighting areas of opportunity in production has shrunk to almost nothing.

Global public investments in renewable energy companies dropped a precipitous 60% in 2012 continuing a free fall from the peak in 2007. Currently, public invest­ment in the sector sits at only one-fifth of the 2007 high. Solar investment fared slightly better than other renewables and claimed the top spot among all technolo­gies, however, this is only because others declined faster. In 2012, solar investment dropped 50% to $2.3 billion globally.[134]

In 2012, global production of PV reached 60 GW for 30 GW of demand.[135] A PhD in economics is not required to recognize the resulting impact on prices with continued slides and lost profitability. Crystalline silicon module spot prices declined from about $1/watt to an average of $0.80/watt and even as low as $0.60/watt on some larger deals.[136]

The resulting slide in prices decimated profits along the value chain with nearly all producers losing money. Many public companies reported staggering losses, while 2012 saw the demise of Q-cells, the German manufacturer that at one time was the largest producer in the world, Centrotherm, a German equipment maker, and Konarka in the United States. Traditional PV was not alone in this mess; Abound Solar, once a darling of the US Department of Energy (and recipient of guarantees similar to those received by the media sensation Solyndra) and producer of thin-film modules, also declared bankruptcy.[137]

It is no surprise that clean energy stocks suffered in 2012, but it is perhaps sur­prising, given the pain in the supply chain, at how little they were down in 2012— 5.9% according to The Wilderhill New Energy Global Index (NEX). The 2012 NEX valuation of 120.02 is down 78% since 2007 and is clearly underperforming against the wider market. Despite these bad conditions, solar remained the largest issuer of shares through Initial Purchase Offerings (IPOs) and still managed to attract signifi­cant investment over the period.[138] The stock valuation was clearly also supported by strength among large developers who are turning in record profits.

The year 2012 ended with a bang, a trend that seems to have continued into 2013. The NEX added 15% from December 1, 2012, to January 31, 2013, with the Bloomberg solar index adding 5%.[139] However, the rebound may be a red-herring and not all commentators agree on the sustainability of the rebound.

The solar industry is clearly offering investors and market analysts mixed mes­sages. As Michael Liebreich, the chief executive of BNEF put it, “for every equip­ment company operating at thin or negative margins, there is an installer who is getting a good deal… Rumors of the death of clean energy have been greatly exag­gerated.”[140] Ultimately, however, solar will not see market competitiveness industry wide until equilibrium is found between installation and production.
